This is all about adrenalin fueled, over the top, and psychotically dangerous racing.
Crashes, as fans of Burnout will tell you, are not done better anywhere else, and they are well integrated into races (after a big crash you have a running start!).
The physics are convincing while the handling of the cars is forgiving enough to permit long drifts and ridiculous jumps and crashes. If you demand realistic handling and simulation from your racing games, Burnout Paradise is not for you.
These criticisms can't detract from what is an absolutely fantastic arcade racing game.
