Well I Love Both You can Choose what you want to do you can adventure and both of them you can install mods!
P.S. Any Of you thinking about Skyrim There might be a Minecraft Mod and On Minecraft There is a Skyrim Mod.
So Basicly they are very good I would suggest haveing oh i dont know one for pc and one for Xbox360 or whatever… That way you can Play Something on your Pc and something on your Gaming System P.S.
Minecraft is MultiPlayer on pc and Xbox360/pc so thats a game you can play with friends and then go solo on Skyrim!
