Yeah they maybe at the age where they find Kirby "too babyish" while not old enough to really see the greatness of everything there. If you want to relive your childhood, NBA Jam is very good. As for Epic Mickey, the decision to go with no voice acting in a game with so much text is strange. Party games might be a good idea. Stick to the nintendo brand in general, though if you kids are boys they might really love Rabids Through Time.
