I hate the "Kiddie vs. Mature" arguments. I think variety is the best thing to go for, which is one reason I chose to get a GameCube instead of some other system. It seems that with the other two big-name systems, more than half of the "great games" I ever see or hear about have a big fat "M" or similar on the front. Not that I would be interested in them anyway, but even if I was, my parents would never let me get games like that. At least with the GameCube, you have a nice mix of everything, they have their share of the great so-called "kiddie" games as well as their big-fat-"M" games for whoever else.
