Sharkie's XNA Game?

While watching a video montage of some games that have been created using Microsoft's XNA software, I noticed one game in particular that could very well be from a certain airplane-loving clan member...

















Even though I doubt he'd spell his own name wrong, we can only hope that Sharkie has been staying up late at night working on a new video game. The profits of course will all go toward the next clan summit.

One part of that video shows the game creation process and it's basically drag-and-drop. If video games could be made that easily and shared over the Marketplace, I think Microsoft might have the next YouTube on their hands. What kind of game would you create?
