Grand Theft Auto: San Andreas (PlayStation 2, 2004)

I think of myself as a hardcore gamer, so I think I would know if this game was fun. From the many accesories you use to make your character unique, to the casinos and horse races, to the wide accesible area that always leaves you wondering what else is out there, this game is great. The missions range from easy to downright insane. Plus, all the new cars and weaponry this is the best Grand Theft Auto to date. But, the rating of this game is there for a reason. I do not suggest you get this for your nephew or niece. But, I say someone about 15 could handle it.
Just think of all the areas you can access and the new things you can install on your ride. Personally, I fancy the GoKart and the racing bike. You may favor the land and water vehicle. Whatever ride you are into it's in this game.
