I don't think that anybody would have the legal ground to sue Microsoft seeing as ho several states tried to pass bills that fined stores that sold M games to underage kids and they were all deemed unconstitutional by the courts (at least in all the states I heard about). If anybody tried to sue Microsoft if they allowed minor to download M content would prolly be laughed right out of court. I think that Microsoft is doing this so they can appear to be "family friendly", which is bullshit. Stupid fear mongers like Jack Thompson scare Microsoft by threating to sue when they have no legal ground, so Microsoft is just trying to protect itself from the PR nightmare associated with them.
Long story short: Microsoft doesn't want you to lie, but they kind of have to force you to because of morons that don't understand that America has something called freedom of speech.
