This is amazing. What I do is something else: I make AI agents develop AI scripts (good ol' computer player scripts) and try to beat each other:

I occasionally run my tournament script: https://github.com/egeozcan/unnamed_rts/blob/main/src/script...

That calculates the ELOs for each AI implementation, and I feed it to different agents so they get really creative trying to beat each other. Also making rule changes to the game and seeing how some scripts get weaker/stronger is a nice way to measure balance.

Funny thing, Codex gets really aggressive and starts cheating a lot of times: https://bsky.app/profile/egeozcan.bsky.social/post/3mfdtj5dh...
