Let's get this out of the way first. If you're under 13, and are playing this game, either your parents don't give a darn or you're stupid. MADWORLD IS NOT FOR KIDS UNDER 13. If you're a parent letting someone under 13 play MadWorld, you must have an excellent explanation for doing so. It's sick, it's twisted, and it's not something that people raised on Mario and Sonic should play...
That does NOT mean, however, that MadWorld is a bad game. FAR FROM IT! MadWorld is the best Mature-rated Wii game ever made, end of story. In MadWorld, you're Jack, a mechanic/ex-Marine with a chainsaw for an arm. The world is overrun with terrorists called "Organizers" that turn the entire city into an over-the-top violent game show where citizens must either kill or be killed. Everything about MadWorld is great except for the camera. That's it. From the beautiful art style (think Sin City meets No More Heroes and you've got the idea set) to the hip hop music (it actually works well) and especially the laugh-out-loud commentary.
Speaking of which, MadWorld is overrun with objectionable content. First off, the violence. It's frickin' brutal, and yet it's not. The violence is graphic and unrealistic, all at the same time. True, the Wii controls make it seem more visceral, but a new study says that Wii motion controls in games like MadWorld, Manhunt II, etc do not instruct people to be violent. Regardless, MadWorld is simply too violent for anyone under 13. If the violence doesn't offend, however, the commentary will. Voiced by Greg Proost (of Whose Line is it Anyway? fame) and John DiMaggio (otherwise known as BENDER), the commentary will make you at least chuckle, or it will start riots at your house. It's extremely offensive. F-bombs fly about once every 30 seconds, Rohypnol (roofies, a date rape drug) and marijuana are both mentioned, and sometimes the sexual references get pretty out of hand (ex. "He should have told him that unprotected **** sex is OK!") Also, in some scenes the female characters are barely covered, but the black and white art style also lessens the impact of this.
Yes, this game isn't for kids. But the comic-book-like art style makes it OK for teens and older, provided they don't impale stop signs in peoples' heads in real life (as if).
