If you're an Xbox Live Gold member, you get access to download (for a limited time) some free digital games every month with your membership. It's pretty cool, and the best part is that you don't have to download them right away. You can just add them to your account and download them later which is especially useful if you're low on space on your console, which is the case for me. So far I've downloaded SSX, Thief and Metro 2033. Currently it's Crysis 3 for the Xbox 360, and Tomb Raider: Definitive Edition for the Xbox One.
