Nintendo should make games for ios.
When I see the success of angry birds and the millions of dollars it has made it makes me think of how successful a mario game could do on the appstore. Not that angry birds and mario are alike but I could easily see mario topping angry birds. I know nintendo only makes games for its own systems but I think they could easily dominate the appstore if they wanted to. I also doubt it would detract from 3ds sales if they only release a very few number of games.
