DM will never be the same it was when I was in college and able to drag my computer across campus to a lounge with all my buddies and frag them face to face.
I think a lot of the "it will never be like XXXX game" has a lot more to do with who and where you played, not so much in the game it is and such.
Halo2 to me is a GREAT game (minus a few nagging issues) but I have SUCH a horrible time playing it when I can't hook up with the xbl buddies I have. Quality of WHERE you play and WHO you play with is a big deal to me.
I think this game, and any other game will be the best it can be when you are in a good place with it.
