You can download user-created games on XBox

Microsoft did something amazing. For XBox 360 users, if you have created your own games, now you can upload them to XBox Live. Not bad, right? I notice that many creative user-created games have been broadcasted through emails or YouTube. Now, I don't need to wait to be surprised. I can just go to XBox Live and look into something fun. Also, I don't need to worry if the games will bring virus to my world. Source: http://www.computerandvideogames.com/article.php?id=182939
