I'm in a video game design class at Virginia Tech, and I designed a poster for a game I'm working on with a team of about 10 people, called "Beacon" - it's going to be a 2.5D side-scroller, and the character's name is Edison.
I put the xbox 360 logo on there, but I don't know for sure if we'll be putting it up on the marketplace just yet. The instructors say if the game's good enough, the school might provide the money to put it up...but we shall see in about a month!
I hope it all works out because I have a 360 and I would love to play it. You should have people sign a petition to send to microsoft to convinve them to make this happen.
