Its still got it
What is more is that if you have Halo CE you can get endless mods for the game, which obviously helps the game push itself above its console counterparts.
Handling
I believe that it is much easier to aim with a mouse than a controller, and a lot of people would agree with me on this. It makes the gameplay much more enjoyable and doesnt lead to you cursing after you hold down the analogue stick down for too long and the camera movement speeds up unaturally and you miss :/
I also think that in Halo 3 there is a feel of less gravity, which may be fine for some, but I find it makes the game slower and detracts from the overall feel of the game.
Well I know a lot of people will disagree with this but its my review and my opinion k?! :P
