Besides, one of my biggest beefs with game companies is putting music in racing games. Didn't think so. While you have production cars in MSR, the feeling is the same. Let me concentrate on the driving. Once the music is turned off, you'll hear a symphony of wonderful car sounds.
Every car has a unique sound as the engine revs.
Audible tire squeal lets you know when you lose grip on a turn. In St. James park, as you rush by trees you hear nice dimensional effects of the staggered trunks. Likewise, you'll always know on which side a car is approaching. There is even ambient noise in the background that is subtle but adds to the realism of the game. If you listen closely on the Fisherman's Wharf courses, you'll hear an occasional horn blow from an offshore boat.
