I have to admit that I'm excited to have Burnout as part of my 360 library. However, it's a little disappointing because of the fact it isn't a real next-gen game. The developers did a great job of porting the game to the 360, but still... if it weren't for the lack of real next-gen games, I wouldn't have bought it. As it is, I am having a ton of fun playing it right now, and that's what counts I guess. This is by far the best version of Burnout ever assembled, and I'd gladly take it over Full Auto any day.
The online mode is the best one I've ever played as it keeps track of your "rivals." It's a great idea and it will bring actual community to online play. The set up pits you against the same people more often... and that's a great way to build a better friends list.
