I have to say I am a skeptical person and I was not sure how it worked but I am never going to purchase the games when I can download them for free. Here is how it works.

I use game copy pro and I rent games and then download them directly to my Xbox. this is much cheaper as the rental is about $5.00 and then I download it to my hard drive. You should try it as it is about half the price of one new or used xbox game.
