On this page if you sign into your xbox live account. You are able to download the free games that Xbox gives for being a gold member. You can also click the link to go shop at Gamestop.
This Page is sort of like a notification page it will tell when you can get new games. When your xbox live membership expires if you dont have the annualy membership. Buying the year membership is really good because you don't have to worry about your game ending because you've been dissconnnected.
