I would consider Minecraft to have the ability at least to create games within its game. So that's fair enough. You can self host your own Minecraft server too (so its decentralized) lol.

Idk I guess I was thinking a purpose built game building game that expressly uses Bitcoin rather than a game that's been appropriated and had Bitcoin built into it, but maybe we don't need to. Maybe just integrating Bitcoin into games that are already around is fine.
