When I was a teen I was mostly writing RA2 custom map scripts and rules/units for my friends and watch them battle with my rules in internet cafes. When that was not possible, I was creating custom RA2 AIs, but it was very hard.

These days, I'm having incredible fun developing good old AI scripts with LLMs, for my own vibe-coded RTS game. Just choose all AI players here to make them battle each other: https://egeozcan.github.io/unnamed_rts/game/

I even let the LLM generate a tournament script to make AI scripts from different LLMs battle (headless): https://github.com/egeozcan/unnamed_rts/blob/main/src/script... GPT-5.5 leaves all in the dust currently. I cannot beat most in the game I set the rules myself :)

If you are like me, you can just make LLMs create your personal RTS game and also develop custom AIs. It's so much fun.

I know you meant player AI, but now I'm imagining an RTS where every unit is running a small reasoning LLM.

I might suck but I found it really hard iirc :^(

Does the project allow AI?

Pitching in on this with a tangent - how good are LLMs with RTS games these days? As someone without friends into that genre, it’d be pretty cool to play eg. AoE II against a capable computer that play like a real human…
