I've got my copy, purchased it this morning at GameStop. I am not that impressed, it's a good game, but I think GOW is way better.... I am really looking forward to COD4. I give Halo 3 a 7 out of ten.
I get my copy from Bestbuy.com Wednesday. And to celebrate, i'm going to a friends house - and not playing Halo3!!! It's going to be fun because it has 4 player co-op. I have tons of friends on Live that want to play with me, so I will have plenty to do for the next few weeks at least. From Friday night - Sunday night it's going to be a Halo3 festivus for the restofus!!!
