Okay, so I successfully beat this game's story mode on 360.  I was impressed and and pissed by this games mechanics.  I was impressed with how my car handled and what I was able to do with the heroic driving engine.  I was aggravated by the fact that my opponents where like bricks traveling at 230 mph.  You could hit them and it doesn't take them out, only you.  If they hit you, it really screws you and you might as well restart the race.  It is a no win situation.  Overall I was happy with the game just wish I could more realistically take out my opponents.
