Question: Why isn't Mario kart working?
Answer: If you got the game straight from the mail and it's not working, you don't owe GameFly everything.
Although, if you broke the game, then you will have to pay for it.
But before you jump to conclusions about the broken Mario Kart, try a few things.
First, clean the disc. Don't use an chemicals or anything, but clean the dust off.
If that doesn't work, make sure it's not your console. Try playing another game. If that other game does work, then it probably is a broken game disc :(
