I wouldn't call it cracking as I still do not think any of the Halo games are as good as people think they are. They are just your average shooters. I wish they would release another Unreal: Tournament game as I love those 10x more than Halo.
Oh come on now! Unreal Tournament is not on the level of Halo! Halo's multiplayer kills it nad the detail, storyline and music score is way above Unreal too,
