I'm too lazy to go back and catalog everyone's contributions -- demosthenes is a more ambition man than I. However, I thought I would make his job easier and at least catalog my own.
Mortal Kombat Scorpion|Sub-Zero
Ninja Gaiden Sigma
Spiderman: Shattered Dimensions
X-Men Origins: Wolverine
There were a few other attempts at the PS3 MK cover in there, but I didn't bother to go catalog them as well.
