Ok. I thought for sure I was going to buy Halo 3 with my new Xbox, but people keep saying that Halo 3 has a crappy campaign and I don't know what. I don't really care how long it is; what's important to me is the different terrain/landscapes that you play on. So could someone please give me a nice lenghty answer telling me what the different terrains are and if they liked it or not. I'm not one too like "indoors" that much, so hopefully halo has a lot of "outdoor" levels.
