I'm surprised FOSS / public domain games don't get more attention and development

Especially now with AI it should be possible to create more open source alternatives to bigger games

I'm kind of surprised there isn't as much of like a core of shared free games more (because if they have some kind of "permissive" license or no license, it's like once they're created they can be shared with absolutely everyone - like families could and should havd giant collections of all kinds of games that are theirs "forever")
