Halo reach was sick. I thoroughly enjoyed the new powers and oddly I liked the sprint power the best. The new assassinations were awesome and some of the new levels were great. I've never really been a COD fan myself. I agree that it is too easy to kill and too easy to die. besides the new cod has a feature where your knife shoots out and will go straight across the entire map killing anyone it hits. lame
While they should put more detail into the combat aspect and reached a happy medium a la Gears or War 2 They chose to be more lenient. Multiple hits kill no matter where they land with most weapons unless they are head shots. Where Halo as in Halo your superman unless I hit you in the sweet spot. But if you jump up and down its harder to reach that sweet spot. Both games have their combat problems and while I don't play gears online I think they got the combat aspect perfect. Just because it takes more precision doesn't make it better. I have only played Halo online twice once on Halo2 and Halo reach. I could get with the guys jumping up and down.
WaW sucked online other than zombies.
