AI War 2 is a true masterpiece of design, one of the most impressive games ever created. In particular, it is a more board gamey take on a 4x grand strategy game. If micromanagement and meaningless but necessary decisions bother you, but you love optimization, this game will be for you. Also look at this game if you want to be able to have huge-feeling campaigns over the course of just a few hours. If you like tactical decisions, it's probably not for you. There are tactics involved, especially in creating a tower defense or selecting an effective roster of ships, but the main way you will handle combat is by putting all of your ships into one or two blobs and slamming them into the enemy. Its mechanics are a bit odd, but they are genius. This changes if you add expansion content, but by default, you are an insurgency, trying to grow strong as efficiently as possible, because every action you take makes the AI stronger as well. You will never be as strong as the AI, but you can become strong enough to topple its homeworlds, before it truly focuses on eradicating you. The opponent you are facing is designed is completely transparent in how it functions, once you are familiar with the game, but there's no cheating those systems, only taking advantage of them to eke out every advantage you can find. It is also a bit hard to get into, but honestly, with the tutorials, a bit of trial and error, and a few questions on the Discord server or steam forum, you can't go wrong with learning the game.

Honestly the game was amazing in concept but struggled even with a good PC due to poor coding for years and years. Enjoyed the early game, and the mid game and then the end of every campaign was so slow it took days to run because of how lagged the whole endevour was. The tech and coding have caught up to an amazing standard. I can now play any concept I can create from start to finish without a massive lag drag. Multiplayer has become way more stable over time. Its hard to believe but in 2026 some companies still seem to care about their product and coding.

Actually good AI. Paradox/CIV players that are used to building fortresses for AI to beat their head against - this doesn't work. Expand too quickly - and the game will be over just as quickly. Winning is very satisfying though

The apex of multi-threaded, well designed AI combined with a mechanically unique asymmetric guerilla-war RTS. You will not find an experience like AI War 2 anywhere else. Don't worry about having Starcraft-tournament level clicks-per-minute, this RTS focuses more on strategy and tactics and is pausable (having your fleets in the right places at the right times, doing the right things). A word of warning, it takes quite a bit of time to get competent. AI War is brutally hard, and it will punish you hard for small mistakes. The reward of this game requires a substantial time investment, and during that time, expect to get your ass kicked. However, if you want a more chill experience, difficulty is highly customize-able, from "if you win this it is a bug" difficulty to "don't hurt me please"/sandbox difficulty. I cannot stress enough how impressive the multi-threaded AI is in this game, it feels like a human opponent. It probes weaknesses, it withdraws from losing battles and uses those forces to create death-balls to kill you later, it hides strike forces from your recon, it ambushes you when you attack a "weak point", it attacks your weak points, etc. Every enemy fleet runs on a different thread in a different CPU core, making absolutely massive battles more performant than would seem possible, although it will choke a bit if the battles get big enough. You can see some lag in response as overloaded threads call back to the main UI at times when you have 20,000 or more ships engaged (on my system). Another impressive aspect is the sheer amount of customization available to you in starting games, from starmap generation, to each AI fleet's behavior, to starting forces, there are hundreds of dials to tweak. This is a must-buy title for anybody who has the time to invest and who loves strategy.
