I was working on a mockup of the Windows Phone Marketplace to test what my game art might look like before it hits the store and all the while I couldn't shake the thought that someone had to have done this already. About halfway though the project during some sidetrack googling I finally managed to enter the right search terms and there it is: Fake Windows Phone Marketplace. Complete with all the necessary pages and lorem ipsum descriptions, the solution's much farther along than mine and relatively complete. So instead of a post with a download to my mockup as previously planned, here's a link to the Fake Windows Phone Marketplace. I believe it would be a useful tool for testing your assets should you hope to find yourself on that all too important featured list someday.
