Which video games do you buy for a 13- year-old? It's a difficult call. While you don't want to give them Grand Theft Auto, you also want to stay away from Care Bears and Dora the Explorer. Thirteen is a vulnerable age; you run the risk of getting something a little too mature, or you could end up insulting them by giving them something well below their age level. Thirteen-year-olds are hard to shop for, so you absolutely must know what you're looking for before you go out and buy anything.
