This game is phenomenal, but I can only play it at my friend's house since I let him borrow my X-Box for the summer (no cable, no computer, nada). He's an adventure/RPG/fighting game guy, so he despises when I want to play PGR2 or 2K5, but that's tough. Too dull and not enough control over the game my ass.
I haven't done anything but create a VIP profile and play quick match games, so I can't say anything about the customization and all that.
The gameplay itself is fabulous, even if I'm having a hard time getting a consistent passing game going (I've always been a bigger fan of the run game). The music at Adelphia Coliseum is great, I discovered when I played as the Titans once. And the "Go Pack Go" is present at Lambeau, so I'm happy.
I won't be able to say how good or bad it really is until I can sink my teeth into the entire game.
