Southern-Otaku

I'm lookin for an online game and an open sandbox-ish game like minecraft seemed pretty fun. i like to think im creative and after seein some of the structures in this game it made me want to give it a shot. any suggestions on the game as a whole? also, what kind of requirements are there? is this a very demanding game? i'd appreciate any comments.
