another random user writes with news that Microsoft has sorted out the Windows Store guidelines such that games rated 'Mature' in the U.S. will be allowed. An earlier version of the guidelines took cues from the European PEGI rating system, which lumps pornographic content into the same rating as mainstream games that involve violence. In the U.S., they're split up into Adult (for porn) and Mature (for things like Skyrim, Call of Duty, and Assassin's Creed). Gamers and developers were worried that a large number of very popular games were going to be disallowed on the Windows Store. Microsoft hopes to have the situation fixed by December — not ideal, since Windows 8 is now out, but better than nothing.
