NHL 2K7

So I guess that Sega’s Sonic will, ironically, be Sony’s platformer face for it’s release, and it’s not even an exclusive.

My recommendations from the list are: Mobile Suit Gundam: CROSSFIRE, Sonic, and one of the racers, I’d probably go with Riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiidge Racer!
