How "Mature" is this game? Aside from the violence that is in all of the games, like being able to beat people up randomly on the street and all that, is there a lot of bad language? Is there any nudity, or sexual content?

I want to get this game, but I don't want the kids to play it if it is too bad. They played GTA 3 and Vice City, but we wouldn't let them play San Andreas because of the way it glorified the thug image and that just hits too close to home. I know the violence won't be a problem because I know they are good kids and are not physically violent by nature. But if the other stuff is excessive then I would hesitate to buy it.

They are 10 and 14 years old. Any information you guys could provide would be very helpful. Thanks
