A : Awww man, do I have to choose? Why not both? Haha.
But really, I have been anticipating Fallout 4 for a long long, it's a dream game to be honest, in which I'd live a different life within the game. The same goes for MC, which I felt alot more alive that the outside world. So I guess for me Fallout 4 and MC is the same thing. Sorry but I wish I could provide you a better answer though :D
