Little Big Planet 2
Much like the previous post of Ilomilo, Little Big Planet owes most of it's success to it's charm and home-made-looking aesthetic. The first one was a commercial and critical success and still remains one of the top played games on the PS3.
With the next installment, LBP2 seems to be everything about the first one, but just...more. Not only are all of the creative tools back, but this time, they've completely opened up the entire mechanic. Beta teams have already made racing games, both kart style and top-down view, third person shooters, spider-man clones, Rube Goldberg devices, vertical scrolling shooters, and much more. And that's just the beta. Along with all this, they are still including all the content people created for the first one. Now with the grappling hook announcement, this game seemingly has no stopping point.
