HALO 4 campaign is like 5 hours long or so I hear.
You guys are so ridiculous. Sure maybe if you're playing on Easy and rush through everything. It took me 5 hours just to get to level 4 in Halo 4. I'm playing on Heroic and it's really hard for me, so it takes a long time and a lot of dying. And believe it or not, dying should count when you're talking about the length of a game. Your time getting better and being able to overcome an obstacle is part of the game!
