Nintendo is going to try to dominate every single age group this generation, that includes the people who normally play M rated games. They're doing too well to try to avoid the largest section of the market. I would like to note that most of the people who play M-rated games also like Zelda, Mario, and Smash Bros. Red Steel sold almost as well as Resistance despite being complete garbage. They may appeal to a broader audience but the fact that over twice as many people have Wiis as the PS3 mean there are still more people playing the Wii who are about the same age group as the PS3. There will most likely be a large selection of M-rated games by 3rd parties by the end of 2008 in addition to a large number of games designed to appeal to the young and the old.
