This was a great one, and I owned it when it was originally released. Still have the CD somewhere.
The biggest fun, and one thing that kept me playing once the intended play got a little old, is where I would spend my time seeing how much damage I could do to a vehicle, and still attempt to drive / race. This is a facet of play that this game maker has decided to leave out of all their follow-up racing stuff. While the new games look unbelievable, you'll discover that the second you crash the car to any real extent, you're yanked out of the gameplay and have to restart. What a drag. If I want to try driving with only three wheels, then let me! They could include an arcade mode, and the only change from normal is that extreme vehicle damage does not end the race. I know it's unrealistic, but it's fun! Turn around on the track and go head-on into the oncoming racers! Letting off some steam and having fun doing a crash-up is great, and looks great on the replay. 1nsane did this right.
Oh, and the multiplayer for this was really great. At 1st there were several servers hosting races and lots of people to play. Lots of custom cars and tracks made for the game. I used to host a race called Wartburg challenge, and only allow the horrid wartburg wagon as a car selection. It really was a fun race, and a nailbighter, when you and everyone else can barely get their underpowered clunker-car going, or over a hill or across a jump. Quite a challenge.
This game was a fun racer, and a great crash-up, much like the fun of Carmageddon 2, where you could literally slice your car in half in a wreck!
