UnknowingFool writes "In releasing the Zune HD, Microsoft decided not to open up software development on the new Zune to third parties yet. Today, Microsoft released a handful of free games for the Zune HD: Texas hold 'em, Sudoku, Space Battle 3, Shell Game, Of the Future, Hexic, Goo Splat and Chess, as well as calculator and weather apps. Users, however, are required to view an ad (up to 30 seconds in length) while the game starts up. While ad-supported free games are also on other platforms, like the iPhone, the difference here is that those iPhone games are from third parties and not from Apple."
