heh, I wouldn't say halo3 is a game for graphic whores, it looks nice and all, but nothing I've seen screams "next gen"
as for the gameplay, I'm going to get halo3, but I'm not even gonna start the single player, only getting it for the multiplayer

, I found both halo 1 and 2 to be very overrated, but when you balance out the multiplayer in halo2 properly, it's really good
btw, I have one friend who is a halo nut, he's taken off 1 week to play the beta release.. I remember back in school, one of my friends didnt come to school for about a month when GTA vice city came out..
