To each their own. I don't play either, and I think that it would be a waste of time.
On the other hand, I think it is some very good engineering work to build a dual core CPU inside a game using only what the game provides.
Yeah well only the japs that actually manufacture them processors can say that it's a processor... I mean I can make some jumbled shit in minecraft and tell everyone it's a homebrew processing unit that is virtual and useless and I wasted countless hours for nothing! yay!
Not saying that it's really a shit, but they sure don't give much facts about it either... just telling about switches on the walls and some lava tracks.
Also the dude filming that video is using a MAC, k? nuff said
