Loan your copy of Crackdown to Eddy Scissorhands? Accidentally leave your Gears of War disc facedown in the driveway? Don't worry about it -- Microsoft will now replace your busted discs (from Microsoft published games) for just $20. GamesAreFun has the details:

How does it work? Mail off the non-functioning game disc along with this form. Your credit card gets charged $20 (USD), and you will receive by mail a brand new copy of your damaged game several days later. Keep in mind that if the CD is actually broken into pieces, you'll have to have more than 90% of the disc for Microsoft to honor the program. And it doesn't cover every 360 game, either, only ones published by Microsoft themselves (complete list below):

-Crackdown
-Fuzion Frenzy 2
-Gears Of War
-Halo 2
-Kameo: Elements of Power
-Ninety Nine Nights
-Perfect Dark Zero
-Project Gotham Racing 3
-Viva Piñata
-Xbox Live Arcade Unplugged Vol. 1

Not a bad deal, considering the alternative is to buy another new copy at full price. Are you sure that you didn't break Fusion Frenzy 2 on purpose, though?
