Open it and have fun man. I was still playing NCAA 07 as late as Monday. Once I got 08, I've not even considered going back to 07 for any reason at all. The game's a little tighter than last year's and just has a better feel to it. The DB's react much better to passes and situations. Not much has changed graphically in my opinion, but the all around game is even more fun that last year's. If you're looking for a complete overhaul from 07, you'll probably be disappointed. If you're looking for a nice upgrade with better gameplay and updated rosters, you can't go wrong with 08. To me, it was well worth my $50. I have the 360 version also and for some reason, still prefer the PS2 version.
