It's not opinion either. It's pure fact. The 360 commercial for GHII has a cool animated style that actually see's you being a guitar "hero". Where as the PS2 version shows you looking like the gaming nerd you really are. Now, I'm sure we all look like a bunch of dorks swinging our plastic guitars around like in the PS2 ad, but I doubt that's what is going to sell the game. The 360 version shows us what we think we look like when we play the game. and what we think we look like looks sooo much better.
For reference, dig the commercials below
