Hey man, it's worth it. Just recently I actually got the platinum for NCAA 11. I don't know if you're on PS3 or Xbox, but if you're on xbox, a platinum is a trophy you get when you unlock all other trophies for that game. I have 2 now. Madden 10 and NCAA 11. I can promise you I'll certainy be gunning for the platinum in NCAA 12.
Anyway, only 17 days. 3 days until the demo, which I won't be in town for... how convenient
