Someone forgot to read the rules of the competition before publishing this story because the comment: "The Dream.Build.Play 2011 Challenge is open to any projects built with XNA Game Studio 4.0, a platform to develop games for Xbox 360, Windows PCs and Windows Phones." is misleading.
The rules state:
"The final version of the Game you submit must be playable by the judging panel on an xbox 360 console...."
Good luck with the PC and Windows Phone 7 games!!!
