@deadrisingizbeast, you DO realize that without Halo the Xbox probably wouldn't have gotten off the ground? And sprinting and barrel rolling came out before Call of Duty and Gears of War. Halo isn't a third person shooter, and it doesn't have chainsaw-guns, so it didn't copy Gears of War. It isn't a modern military shooter, it doesn't have ADS, and it doesn't have a plot recycled from almost every Tom Clancy novel, so it didn't copy Call of Duty. It follows its own plot without trying to have one that resembles other games. Call of Duty is an amazing franchise, but its influence on the Xbox as a console isn't as great as Halo's. If you don't like Halo, that's fine. Just make sure you get your facts straight before you bash it.
I just wish that people wouldn't automatically say Halo sucks, because without Halo, console multiplayer would have taken longer to start up. So people couldn't play their precious MW2. Also, I wish that parents would actually read ratings and not let their 7 year olds play M rated games so we wouldn't have to deal with whiny kids calling us hackers and annoying the hell out of us.
