Worst racing game I ever played.
-It's got a built in rumble feature.
The Bad:
-The moment I touch a car or get off road I spin out. If a touch the rumble strip, my car stops. The only fun I got out of this was driving by myself, as it's pretty much impossible to race with a full field.
-The most annoying sound EVER. Whether it's the music or the engines, it all sounds horrible.
-Only 3 tracks...3 very boring tracks. And you can't even choose a car.
-At the end of each race I couldn't figure out how to get back to the menu, so I just had to shut my Gameboy off.
Seriously, don't buy this game. If you like Nascar, get anything but this. It is by far the worst racing game I've ever played.
