I'm usually a fan of open source games but rarely do they manage to be actually great. People like giving recommendations like Super Tux Kart that haven't aged well and don't play well. What are some open source games that are legitimately good that I've missed?
Minetest is the engine, MineClone2 is the game. Minetest has a default game (Minetest game), which has no mobs or anything. It's dull without mods. MineClone2 is recreation of Minecraft on Minetest, but with some differences. For example, you can use a burger to lure villagers. It's great fun and worth a try.
