For the long history of such games (where people actually wrote the rather simple AI code for their avatar), take a look at RobotWar and its various later clones like C-Robots and Omega.
thanks! I didn't know about Robotwar and its fascinating, I just wanted to democratize this through normal english prompts, so anyone regardless of their coding ability can participate. Tbh this has been a dream of mine since childhood but I never had the ability to execute until the dawn of Cursor, Claude, and v0 :)
