A good laugh.
While watching this, I can't help but wonder how many people will say "OMG G4M3CuB3 SUX0RS!!!" and the sort. Heh.
Anyway, on with the review.
Your art style is nice. Sure, there could have been an extra amount of detail, but very nice, I say. Sound...well, not in my tastes. But who cares what I think about music like that, eh? And, your menu choice needs some work. It's hard to tell what you're grabbing and what you've grabbed to trick out your Gamecube.
Actually, this would be cool as a series. Like, a Pimp My Wii, or my 360, or my Atari Jaguar. Be creative, do whatever! Well, luck for the future.
