I honestly don't know how I missed this piece of news. I didn't even want to share the news as I wanted to keep it all to myself :).
Have you been messing around with XNA? If so, do you want to see your game on XBox Live Arcade? I know: who wouldn't. But you never know :P. If you would love to see this, there's an upcoming contest just for you: http://www.dreambuildplay.com/index.html. The prize that is currently hinted at is that the winner's game will be posted to XBox Live Arcade for everyone all XBox users to download and play.
Now that's just wicked cool!
