6 hours for 4 people is pretty good....for 1 person thats 10+ hours, great for any fps. But honestly, once I touched multiplayer and saved films I almost completely forgot about single player and coop. They are just so fun I could see it being a while before I actually finish the campaign.
The one thing that annoys the hell out of me is how much I suck at halo. I have been playing fps games since I was 8 years old, starting with Doom 1 and 2, Quake 1 and 2, all the unreals and unreal tournaments.....etc. etc. etc. etc. the list goes on forever. Whether it was single player or online, if it was an fps I was playing it. Rarely did I join a deathmatch game and not come in at least 3rd.
However, this BASTARD Halo 3 is kicking my ass. It's such a different feel from other games, and that is part of what makes it so fun. At the same time though, when I am getting pummeled, it brings my piss to a boil and I curse all these losers who spent 50000 hours playing Halo 2, which I never played because it sucked. Its like everybody is an expert at that game: little kids, ghetto wannabes, country bumpkins, canadians, nerds, jocks, gays, brits, no matter who you are and what you do YOU are amazing at Halo 3. I am not however, and my brain constantly feels like it is being stabbed and raped as it searches for the answer.
