If you're into RTS, Starcraft 2 is basis for a bunch of research and has an API available - see https://github.com/deepmind/pysc2 or a tutorial for getting started https://njustesen.com/2018/01/16/getting-started-with-the-st...

DOTA had also decent API links as far as I recall.

Also, there's a lot of research on older games, see https://github.com/openai/retro for interfacing with NES/SNES/GBA/etc games.
