@admitsWrongIfProven I just don’t trust myself I guess. Would that involve having a separate router to wall off my network? And doing stuff like fail2ban and disabling login via password to the pi?

I think you can actually host the classic java version or the new “bedrock” edition.

My third thought was there are open source voxel games that I could try and potentially host. Minetest comes up over and over but I really liked Terasology the most from this list: https://opensource.com/alternatives/minecraft
