I've been following this one since it was in getdeb. debian picked it up and it seems to continue to be maintained. There are also 24 mods in the repo as well. If you feel like giving it a try, here's info on getting started, game controls, the forum, FAQ, a good article in Linux Magazine and for development a minetest modeling book.Minetest. ... While Minecraft is a proprietary completed sandbox/survival game, Minetest is a free software work-in-progress game engine which supports various voxel games in the likes of Minecraft, InfiniMiner, etc. See Games for more about this. It also allows modding at its core.
