Split Second is awesome, a bunch of us play it on Friday nights...
Gameplay itself is intense, but there are quite a few problems with the menus and usability of the game. For instance there is no in game chat, and hooking up with friends is a pain if you are not using something like teamspeak to send invites to the lobby you are in. They did so well with the game, but failed miserably at the interface/usability....
