lol I've always been weary of IGN and Gamespot, since they've both always been a little biased towards the 360.
Case in point, Castle Crashers was recently released for the PS3. Despite having all features of the original and more (new minigames and stuff) they gave it a lesser score than it's 360 counterpart.
Namely they complained about it being overly long, despite it being the same as the original, and being too hectic with four players, again, just like the original. The only gripe they added was that the PS3 volleyball mode was lousy, despite complaining about not enough stuff to do on the 360 version.
Forgive me for my ignorance, but I don't really see any valid arguments.
I've always been fine with games being rated better on one system over the other, IF they have good reasons for being rated so, such as having a choppier frame-rate on one over the other, or having some other problems, like gimped controls or annoying glitches. I've always thought that both IGN and Gamespot are more biased towards the Xbox 360, so I'm not surprised with this review to be honest. If it were for PS3, they'd have given it a 9 or something. XD
