Favorite thing? The feel of the game. The camera angles on vehicles, the armor customization(limited to several good choices, but not excessive like Reach), the physics that make driving a Warthog "possible". Playiing as an Elite that DOESN'T look like a freak like in Reach. And, of course, all the great BTB CTF Matches on Standoff Heavy. Still playing it, and although I'm getting Halo 4, I'll go back to it every once in a while. Just to see how things used to be.
