Slick crash effects. Open world racing done at its best. Better then expected. Seemless online interaction with others.
The other flaw is that open racing means you can get to the finish anyway, but leads to driving down the same roads most of the time.
Online is a blast with friends, but some kids want to do nothing but crash you and ruin your fun, especialy when doing challenges. Also the 'Set-up' crash intersections are gone, replacing htem with an arcadey crash anywhere style. Its ok but not the highlight of the game.
All in all its a well done game that evoled the classic series to the next-gen.
