Can't Stop! The World of Autobattlers & Idle Games

Hello everyone!

Today, I'd like to introduce some of my personal favorite autobattlers and idle games that I highly recommend.

Although they're often grouped together under the label of "autobattlers," the genre actually covers a surprisingly wide range of games. On one end, there are deep, strategy-focused titles inspired by Final Fantasy XII's Gambit system, where you carefully plan your tactics in advance and then simply watch your strategy unfold during combat. On the other end, there are more casual games that require little preparation and can be enjoyed with a few taps on your phone.

Despite being a fairly niche genre, autobattlers and idle games are much more diverse than they first appear.

In this article, I'll introduce the autobattlers and idle games that I've personally played and especially recommend, along with a few upcoming titles that I believe are worth keeping an eye on. I'll also explain what makes each one stand out and why I think they're worth your time.

What is the Gambit system?

The Gambit system, introduced in Final Fantasy XII, allows you to program your party members' behavior before battle begins. By creating conditional rules such as "If HP is below 30%, cast Cure" or "If an enemy is weak to Fire, cast Fire," your characters will automatically carry out those actions during combat without requiring direct player input. The result is a combat system that emphasizes planning, strategy, and optimization over fast reflexes.

With that out of the way, let's dive in!

Note: This article is a revised copy of one I originally wrote on June 9, 2025.
ChatGPT Translation.

Breeder

Let's start with the very first autobattler I ever played.

It was a robot battle strategy game released for the NES Disk System. Although it didn't let you fine-tune your AI the way modern games do, you could customize broad parameters such as your robot's jump ability and weapon power, as well as choose its body type, such as a biped or hover unit. You could then pit your creation against robots built by other players, which was remarkably innovative for its time.

The game also allowed you to adjust a few AI-related parameters, although I don't remember them making a huge difference in how the robots behaved.

Back then, one of my closest friends and I spent countless hours designing robots and battling each other. My undefeated hover-type robot, Blasty, seemed unstoppable... until one day my friend's snake-type robot simply kept slithering away from me. My robot eventually ran out of fuel while trying to chase it and lost the match.

I still remember being so frustrated that I actually cried over that defeat. Looking back now, it's a funny memory, but I think those battles with my friend may have been what first sparked my lifelong fascination with autobattlers.

Unicorn Overlord

This is, without a doubt, the autobattler I recommend more than any other. In fact, it has become my favorite game of all time, regardless of genre.

Everything about it is exceptional. The beautiful pixel art is stunning, the soundtrack is fantastic, and above all else, I was completely captivated by its combat system, which carries on the spirit of Final Fantasy XII's Gambit system.

I honestly struggle to find anything to criticize. As far as I'm concerned, it's as close to a perfect game as you can get.

If I had to point out one minor drawback, it would be the story. Perhaps because of its open-world structure, the narrative feels relatively straightforward. Players expecting a dense, intricately woven story like 13 Sentinels: Aegis Rim, another title by Vanillaware, may come away a little disappointed.

That said, I believe this was the right decision. The game's greatest strength lies in its meticulously crafted gameplay systems, and keeping the story relatively light allows those systems to take center stage without interruption.

If you're a fan of autobattlers and haven't played Unicorn Overlord yet, I wholeheartedly recommend giving it a try. It's an experience you shouldn't miss.

Final Fantasy XII

No introduction is really needed. Final Fantasy XII is the game that brought the Gambit system into the spotlight.

There may have been earlier games with similar ideas, but Final Fantasy XII deserves tremendous credit for introducing the concept of the Gambit system to a worldwide audience and demonstrating just how engaging programmable party AI could be.

Alongside its outstanding story, written by Yasumi Matsuno and set in the rich world of Ivalice, the game's elegant and highly refined combat system continues to captivate players to this day.

One of the most brilliant aspects of the design was how you gradually collected new Gambits, allowing your party's AI to become more sophisticated over time. The progression felt perfectly paced.

At first, your Gambits might be as simple as:

• If an ally's HP falls below 50% → Cast Cure.

Later, you could create much more elaborate behavior, such as:

• If my MP falls below 30% → Use an MP recovery item.

• If an enemy is weak to Fire → Cast a Fire spell.

• If an ally is Blinded → Use an Eye Drops item on that ally.

Building these conditional behaviors almost feels like writing a simple computer program. It can seem a little intimidating at first, but once you get the hang of it, it's incredibly satisfying. Optimizing your party's AI becomes addictive, and before you know it, you'll find yourself constantly tweaking your Gambits in search of the perfect strategy.

Tactics Ogre: Reborn

Strictly speaking, it's debatable whether Tactics Ogre: Reborn qualifies as an autobattler. However, since it's another game directed by Yasumi Matsuno, I'd like to include it here.

Originally released for the Super Famicom, it was a tactical SRPG featuring an isometric battlefield. Decades later, it was revived in the Reiwa era as Tactics Ogre: Reborn. Even back on the Super Famicom, the game was praised for its outstanding story and well-crafted gameplay systems, both of which have stood the test of time.

The reason I'm including the remake in this list is because of its post-game content. Once you reach the endgame, the AI battle system becomes not only incredibly useful but also genuinely entertaining to watch.

The original game did feature AI-controlled battles, but given the hardware limitations of the time, the AI wasn't particularly sophisticated. It was mostly useful for making Training Mode less tedious.

In Reborn, however, the AI has been significantly improved. During the endgame, especially while exploring the Palace of the Dead, a massive dungeon with over 100 floors, relying on AI isn't just convenient, it's practically essential.

Of course, simply handing everything over to the AI won't guarantee victory. If you do that, your party will often get defeated. However, by carefully optimizing your equipment, skills, and party composition, the AI performs remarkably well.

And that's exactly what makes it so enjoyable. Experimenting with different builds, refining your strategy, and watching your preparations pay off is a satisfying experience in its own right.

Algolemeth

This is an upcoming game scheduled for release on Steam later this year, and its gameplay strongly reminds me of a true successor to the Gambit system.

As you explore 3D dungeons and fight your way through enemies, you'll gradually collect new strategy modules that can be combined to create increasingly sophisticated AI behavior, much like Gambits in Final Fantasy XII.

When development first began, the game featured simple graphics and no music at all. However, as positive word of mouth spread, it steadily gained popularity, allowing the developers to significantly improve both the visuals and the overall production quality.

Most exciting of all, the soundtrack is being composed by Yuzo Koshiro, the legendary composer best known for his work on Ys, Sorcerian, and more recently Etrian Odyssey.

Personally, this is the autobattler I'm looking forward to the most.

One feature that especially caught my attention is something I've never seen before. The game doesn't just automate battles, it can also fully automate dungeon exploration itself. Once you've set up your routines and strategies, your party will fight enemies, navigate the dungeon, and continue exploring entirely on its own.

That makes it the perfect game to enjoy while working on something else, since all of the fun comes from designing and refining your strategy beforehand and then watching it execute automatically.

Three Kingdoms Mushouden

This is another Steam title, scheduled for release on June 17, 2025. At the time of writing, the full game has not yet been released, but after playing the demo, I found it to be exactly the kind of game I love. It combines an auto-battle system with gameplay that strongly reminded me of the classic Battle Brothers.

In the demo, only a single protagonist was available. In the full release, however, you'll be able to choose from around five different protagonists. From there, you'll recruit companions, complete quests, manage your finances, and gradually build your own force.

The demo alone offered around ten hours of gameplay, which is an impressive amount of content for a trial version. Unfortunately, by the time this article was written, the demo was no longer available to download.

I'm also grateful that the game includes Japanese language support. If it's possible to recruit famous historical officers as your subordinates, I think the game will become even more enjoyable.

While it doesn't appear to be quite as punishing as Battle Brothers, it still looks like a fairly challenging game. Players who enjoy strategic decision-making and carefully building up their company will likely feel right at home.

Tactical Chronicle

This is a free game that carries on the spirit of the Gambit system.

Its graphics are fairly simple, but the gameplay is so polished and sophisticated that it's hard to believe the game is completely free. If you enjoy autobattlers and have some time to spare, I strongly recommend giving it a try at least once.

The story is set in a slightly comedic medieval fantasy world. There are also plenty of side quests, making it a surprisingly substantial game with a great deal of content.

When I first discovered it, I was genuinely excited because it felt like uncovering a hidden gem.

Even if you normally hesitate to play freeware games, please give this one a chance. You may find yourself completely hooked by the depth of its systems.

mystery of fortune3

This game was originally released for mobile devices.

While its AI system isn't as deep or flexible as the Gambit system, it still gives players a surprising amount of freedom to customize their party's behavior. Once battle begins, your characters dash around the battlefield in real time, each carrying out their assigned roles automatically.

The game features a variety of classes, including tanks, healers, and damage dealers, allowing you to experiment with different party compositions and strategies.

Unfortunately, the mobile version has since been discontinued, and the sequel that was available on Steam has also been delisted.

It was a genuinely enjoyable game, and I sincerely hope it finds its way back someday in one form or another.

Agent of Adventure

This is another mobile game, and although I've only recently started playing it, I've been enjoying it quite a bit.

Like many idle games, you begin by giving your adventurers a few simple instructions and then let them carry on by themselves. However, what really sets this game apart is its rich tabletop RPG-inspired mechanics and its classic fantasy setting.

At the beginning, your adventurers' village is little more than an empty settlement. As you progress, you gradually construct new buildings such as blacksmiths, taverns, and other facilities, slowly transforming it into a thriving town.

You recruit adventurers at the tavern, equip them with weapons and armor crafted in the shops you've built, and then send them off on their adventures.

There is also a wide variety of classes to choose from. In addition to familiar roles like healers and tanks, there are more unusual professions, such as cartographers, each contributing to the party in different ways.

To be honest, many of the game's actions are a little cumbersome and not especially user-friendly. However, if you enjoy immersing yourself in role-playing and don't mind a slower pace, those little inconveniences actually become part of the charm.

Another feature I really appreciate is the built-in automatic translation system for guild chat, which makes it easy to communicate with players from around the world.

Since each expedition can take several hours to complete, you can prepare your party, send them on their way, and then spend your time doing something else while they continue their adventure. It perfectly captures the appeal of an idle game.

Carnage Heart

To be honest, I never managed to finish this game when it first came out. Its systems were simply too difficult for me.

What you're doing is essentially programming. Rather than directly controlling your robots, you design their behavior by creating logic that determines how they should react in different situations.

Even so, I was fascinated by the concept. If I had the skills of a programmer, this is absolutely a game I would love to dive into.

I was able to create some simple routines in the early stages, but as the game progressed, the programs became increasingly complex. Eventually, I reached a point where I could no longer keep up and had to give up.

If you're comfortable with programming or have an interest in giant robots and AI, I think this is a game well worth trying.

The only downside is that it was released on older platforms such as the original PlayStation and the PSP. These days, setting up a way to play it may be the biggest challenge of all.

GLADIABOTS - AI Combat Arena

If the idea behind Carnage Heart interests you, then this is the game I'd recommend instead.

The easiest way to describe it is this: it's essentially Carnage Heart on Steam.

The graphics certainly aren't its strongest point, but the underlying systems capture the spirit of Carnage Heart remarkably well. Besides, I doubt many people are looking for cutting-edge visuals in a game like this anyway. (Maybe that's just my bias.)

The game offers several different modes. In addition to straightforward one-on-one battles, there are team battles featuring multiple robots on each side, as well as a soccer-inspired mode where the objective is to score goals by getting a ball into the opponent's net.

It also introduces a number of quality-of-life improvements. For example, you can save commonly used routines as reusable modules, making it much easier to build and manage more sophisticated AI programs.

Best of all, it's available at a very reasonable price, making it an excellent entry point for anyone interested in programming AI-controlled robots.

Armored Core: Formula Front

We're sticking with giant robots for another entry, but this game takes a much more approachable approach to AI.

Rather than focusing on writing complex AI routines, the emphasis is on building your own Armored Core mech and watching it battle against other machines. The fun comes from designing the perfect machine and seeing how it performs in combat.

In many ways, it feels like Carnage Heart with all the complicated programming stripped away. Instead, the focus is entirely on customizing your mech and enjoying battles between robots that you built yourself.

Lootun

I hope you'll forgive a bit of self-promotion, but I'd like to recommend the autobattler that I've personally spent over 400 hours playing.

Originally, a volunteer created a Japanese translation using machine translation in just a few hours. I wanted to improve its quality, so I spent several months personally revising and polishing it.

My translation is still far from perfect, and there are plenty of rough edges. Even so, after many twists and turns, I eventually managed to complete the project.

As for the game itself, it doesn't offer the same level of AI customization as a true Gambit system. Instead, it's a more traditional autobattler where you prepare your characters in advance, decide on their overall strategy, and then sit back as they fight automatically.

The graphics are fairly simple, but one feature I really like is that you can use any image you want as the game's thumbnail. It's also the perfect game to leave running in the background while you work on something else. Before you know it, you've spent hours playing without even realizing it.

Auto Rogue

To be honest, I haven't played the full release of this game yet.

I'm currently busy working on another game's machine translation project, so I'd like to take my time and enjoy this one once that's finished.

I did play the demo through to the end, though, and my first impression was that it was an exceptionally well-crafted game.

Like many of the games on this list, it features a Gambit-style system. You control a single adorable white creature, combining different skills and refining your strategy through repeated trial and error until you find a winning setup.

The game's atmosphere and world are also wonderfully charming.

It's been featured by quite a few content creators and streamers, so there's a good chance many of you have already heard of it.

TRADESMAN: Deal to Dealer

Since I've already been shamelessly promoting my own favorites, let me sneak in one more recommendation.

This game didn't originally support Japanese, but I fell in love with it and am currently working on a Japanese localization.

If I had to describe it in one sentence, I'd say it's the perfect game for anyone who loves autobattlers, trading, and cats.

Imagine a simpler, 2D take on Battle Brothers. You play as a traveling merchant, buying goods where they're cheap and transporting them to towns where you can sell them for a profit. It's a straightforward premise, but the journey is anything but peaceful.

Along the roads you'll encounter all sorts of enemies, from farmers armed with chickens to giant boars and even Bigfoot, all eager to steal your cargo. The greedier you are and the more goods you load onto your wagon, the heavier the penalties become, and the stronger your enemies grow. To survive, you'll need to hire capable mercenaries to protect both you and your merchandise.

One of my favorite things about this game is its wonderfully quirky writing. It's full of satire and clever humor. For example, there's an item that is obviously sushi, yet instead of calling it sushi, the game describes it as "Rice with Fish (A foreign delicacy enjoyed by fishermen, poor people... and just about everyone else.)" Little touches like that constantly made me smile while translating.

There are also adorable cats wandering around every town. If you click on one, it lets out a cheerful "Meow!" before trotting away.

The game even features a skill called Catmancy, a playful combination of cats and necromancy. While Catmancy works perfectly well in English, I renamed it Nyacromancy in the Japanese version to make it sound even cuter and to preserve the feline wordplay.

I actually completed the first full machine-translated version some time ago. However, once I played through the game with the translation in place, I found quite a few awkward lines and mistranslations. So I'm currently doing a complete playthrough, carefully polishing every line as I go.

I'm almost finished now, so I hope to release the Japanese localization very soon.

Legends of Dragaea: Idle Dungeons

This is another game available on Steam.

It doesn't feature a Gambit-style system, but it follows the familiar autobattler formula of preparing your expedition party, sending them into the dungeon, and then sitting back to watch their adventure unfold.

What makes this game stand out is its fully 3D dungeon exploration. The movement is surprisingly smooth, making it much more dynamic than you might expect from an autobattler.

I've only played the demo so far, but it left a great impression on me, and it's definitely one of the upcoming releases I'm looking forward to the most.

SUMMER ROAD 10-Minute Auto Roguelite

Next up is another game coming to Steam.

Its most distinctive feature is its unique visual style. The artwork has a warm, nostalgic charm that immediately reminded me of EarthBound (MOTHER 2).

From what I've played, the game is about watching a group of boys explore and adventure in real time. Most of the time you simply observe them, occasionally giving simple instructions while letting them carry on with their journey.

The game hasn't been released yet, but it's definitely one of the upcoming titles I'm looking forward to the most.

Granblue Fantasy

With the Steam games covered, let's move on to the well-known Granblue Fantasy.

I'm generally not much of a mobile game player, but this is one I've become quite hooked on recently.

The visuals are charming, the characters are fully voiced, and while the combat isn't completely automated, it mostly consists of tapping your phone as battles unfold. The controls are simple enough that you can relax and enjoy the game without having to think too hard.

Combat revolves around an elemental affinity system, similar to the weapon triangle in Fire Emblem. Water is strong against Fire, Fire beats Wind, Wind defeats Earth, Earth overcomes Water, while Light and Dark are strong against each other.

Character progression is also fairly typical of the genre. Personally, I've never been a fan of the often overwhelming upgrade systems found in many mobile games, but Granblue Fantasy feels relatively straightforward by comparison, making it much easier to get into.

Another nice touch is that the official YouTube channel regularly uploads detailed guides and strategy videos. It's a thoughtful resource for both new and experienced players, and something I really appreciate as a player.

SUPER METAL CRUSHER

This is a game for the PC Engine.

Like Breeder, which I mentioned at the beginning, you simply choose your robot's type and adjust its parameters before sending it into battle. Once everything is set up, the fights play out automatically.

Since it's a fairly old title, it may be a little difficult to get your hands on a copy these days.

It's such a simple game that my introduction ended up being pretty simple too! lol

Nobunaga's Ambition Online

Finally, I'd like to introduce one last game.

This one is an online RPG where you can recruit soldiers and give them orders using a system very similar to Gambits. It's quite unusual to see this kind of AI customization in an MMORPG, isn't it?

Although it wasn't the game's main feature, I remember being able to create surprisingly detailed battle strategies for my soldiers.

The game itself is quite old, dating back to the PlayStation 2 BB Unit era, yet it still appears to be running today. The fact that it's still alive after all these years is remarkable in itself!

That also makes me wonder: since it was released during the PlayStation 2 era, which came first, Nobunaga's Ambition Online or Final Fantasy XII? lol

The Appeal of Autobattlers and Volunteer Machine Translation

I've been lazy ever since I was a kid.

In fact, even the personality test in the Dragon Quest III remake labeled me as "Lazy," so I guess it must be true.

For a long time, I assumed that because I was lazy, I'd never be able to stick with anything. But while I was attending a computer vocational school, one of my teachers told me something I'll never forget:

I don't know whether that conversation was the turning point, but looking back now, it probably was.

Today I use AI to assist with machine translation, and I enjoy games that automate battles. Anything that can automate a task naturally fascinates me.

It all started with a rather selfish thought:

"Maybe even a lazy person like me can create something valuable."

That simple idea led me into the world of volunteer machine translation, and before I knew it, almost a year had passed.

Very soon, I'll be completing the third volunteer machine translation project I've worked on.

People get to enjoy games in Japanese. I get to play the games I love in my native language. And, as a bonus, every completed project gives my self-confidence a little boost.

For me, volunteer machine translation and autobattler games are like catnip. Once I discovered them, I simply couldn't stay away.

Thank you very much for reading all the way to the end.

I know this is a very niche topic, so I honestly don't expect many people to read it. Even so, I wanted to fill this article with as much of my passion and love for autobattler games as I could.

If you know of any other interesting or unusual autobattler games, I'd be delighted to hear about them. Please let me know in the comments.
