I am a former Minecraft player and fanboy. However, I recently started boycotting Micro$oft after controversial actions towards Linux(like patenting convergence).
At that time I decided to pick up Minetest, a game I had on my Linux laptop just out of curiosity. I was initially struck by the lack of creatures and some of Minecraft's other features, so I decided to modify the game. Eventually I settled with the subgame "Minetest: The Next Game." It has all of the features I need (except for compatibility with the hunger mod)
I am already developing a texture pack for the game that is a port of my favorite Minecraft texture pack. You will find it in the texture packs forum. If I can learn enough Lua, I might also try to write mods. All of my projects go under either the CC-BY-SA, CC-BY-SA-NC, or GPL. I am a tech slacktivist and am very anticommercial. Enjoy my presence here.
If you want to contact me, I'd gladly chat you on Twitter(gunvolt_linux) or GNU Social(gunvolt@quitter.se)
