Yeah... I define teenage games as over-the-top violence and adult games as just being challenging, complex and fun (as adults don't require massive amounts of unrealistic gore to enjoy a game). Most games with characters with personality I throw in as adult games too, as the average teenager doesn't care about storyline. Obviously no particularly violent games are targeted at kids (though I have 2 8 year old cousins who play GTA...), but neither are games like Mario. What they are targeted at is families. No one actually targets kids as a primary audience (other than a couple 3rd party games), despite popular belief of 360 and PS3 fanboys. Kids are in fact the smallest market in gaming. In fact, 80% of the Wii's marketing budget is to target ADULTS http://www.joystiq.com/2006/11/12/nintendo-wii-marketing-to-exceed-200-million/
