It has a decent story mode, many characters to unlock, and one of the most enjoyable multiplayer modes

Other than that, I really didn't feel there was much else besides all the cool codes (like all the weapons codes and stuff) and that you could be so many people in the multiplayer mode like Officer Barbrady, Mr. Mackey (M'kay), Terrance and Phillip and if you really wanted to, Starvin' Marvin
