That's why I've played, actually. I wanted to get sorta acquainted with the controls to kick the **** out of the kids on it. They got 2 controllers recently, so we now play each other and their friends when they're over, and POWN!!!!1111 each other. Very fun.
I didn't dig HALO1 either though and played it to completion... Just wasn't into it much I guess. I much prefer the gaming engines of Call of Duty, Medal of Honor, Brother's In Arms, etc.
