Realistic? Not Really. Fun? You bet!
I played this about 5 years ago on my decked out 386. :)
I love this game. It doesn't have the best graphics, The sound is adequate, and the controls OK.
Although these are the games shortcomings, this game is completely addictive. The tracks that are included range from easy to challenging. But the great things about this is the track editor.
Creating your track is pretty easy. You have a Grid of sorts and pieces of track that you place down to create the track. Quick, easy and simple. I used to trade tracks with friends and try to make the best time to complete laps. A great competitive game in that sense.
The physics engine was not the best, but taking jumps and missing the landing ramp... or hitting a steep incline and making your car SOAR into the sky.... Or just witnessing an awesome crash over and over (thanks to the built-in replay camera) is just too fun.
There wasn't a lot I didn't like... It was a great game!
The Bottom Line
A racing game that you can't take seriuously. Great fun.
