I freakin love Halo 3. It's hard (sniping, shooting, ect.). That's good because little kids won't be good in this game, just like Halo 1. The older crowd will master this game, no more little kids talkin ****. Halo 2 was too easy. AR ftw!
Dang my girlfriend just bought it for me tonight...pretty fun game! I didnt start playing campaign though, just some multiplayer with the friends.
