And every game with cartoony graphics is made for little kids?

Like OnyxMeth said, Mature is the name of the rating, and that's it.

For example, "what about the film The Dark Knight was restricted? How was it a restricted film?"

The most mature game is Brain Training. Wii Fit's pretty damn mature too.

How?

Okay, so I watched the ZP video. I haven't seen one in a while. Has he just been pointlessly bashing the system in his game reviews for a while now? He pointed out several times that his main problem with the game was that it was on the Wii. I thought he was kidding at first, since he said the other 2 consoles are just fighting over who gets to have more titties and blood. But then he kept saying it over and over. Is he constantly bashing the Wii now? And what was with dissing Viewtiful Joe in there?

Trying to fix your spine and pelvis alignment through posture exercises and yoga.  That's not for kids, since they don't have back problems.

Seriously that accounts for a review?

If any of us wrote that dribble he said then we be banned so fast from any forum. In fact I suspect that kind of logic from gamefaqs or gamespot system wars.

Most posture troubles actually are born  when the kids first start spending a lot of their time at the school desks.

But if that is really your definition of mature content, then I can't wait for "Ultimate Taxxx Form" and "Dentures Wars: Gum Irritations Strike Back" :)

Those will definitely be the most mature games ever made, but the least Mature.  I'd try Denture Wars if it had a bunch of minigames that taught me about dental care, but not if it was just a self-help game.  Or they could make an educational dental version of Trauma Center that could be really hilarious.

I wish I had Wii Fit for my back when I was a kid.  But I still think it's more mature than MadWorld.

AKA best magnet for teenagers.

Anyway, I'd say that it's mature in the same way that "Itchy and Scratchy" is mature: as a satire of excessive gory violence in media and its exploitation.

You don't need a mature gameplay to send a mature message.
