It's quite simple really, OP. The constant use of 'best game evar' to refer to PS3 games a simple case of base irony. Everyone knows the following two facts:
1: All those games are for the PS3
2: The PS3 doesn't have any games.
Ergo, God of War 3, Killzone 2, and Uncharted 2 don't exist, and are merely an elaborate in-joke among PS3 fanboys. FF13 exists, but only for the 360. By saying they are the 'best game ever', you purport to have played these mythical/fictional games, which is patently ridiculous, and claiming they are all the 'best ever' isn't contradictory, because none of them actually exist.
(I need to stop drinking so much. I can't tell if I'm trolling or counter-trolling)
Wii has more 20 million sellers than PS3 has 5 million sellers.
