Lets be fair with this comparison.
Let's compare a top-tier PS360 game with Conduit, since it's a top-tier Wii game. Right?
For 360, we'll go Gears 2
PS3, Killzone 2
Wii, Conduit
What did these pictures prove? Nothing we didn't already know, but it's not fun comparing games that aren't fair is it? Not a top-tier game compared to shovelware, or a game on a HD console to a game on a non-SD console.
