NO, that can't be said. In Halo you are equiped with a variety of weapons, all of which have the same basic purpose - killing stuff. You plow through hoards of aliens, blasting and shooting, and certainly that can be fun... it just doesn't make Halo in any way different from say Goldeneye (O.K. the Halo graphics are slightly better...). But with something like Mario Galaxy, no two stars are the same and you've always got a different mission to complete. But, hey, I'm not saying Halo's rubbish, far from it. I've played through one and two on co-op and really enjoyed them and at the end of the day it's just about what type of game each individual likes to play and rubbishing the others consoles just seems a waste of time.
P.S. Didn't mean to be argumentative.
