THE BAD:
No sound while driving "In Car View", just the game music. Imagine racing at 200+ mph with no engine noise!! This makes for a VERY unrealistic gameplay. It also makes it very difficult to know when to shift gears (for those who listen to RPM's to shift). Also when the engine climbs through RPM's (in Normal Car View) it sounds almost like ATARI racing games(a separate sound for each MPH), unlike the smooth climb through in RPM's in the original INDY CAR SERIES.
SUMMARY:
I should have rented this game before I bought it. The original Indy Car Series game is much more fun to play and realistic. Being a huge fan of the IRL (Indy Racing League) and spectator of the Indianapolis 500 this is a let down. This game is not recommended.
