You have to keep in mind that most computer games are actually played by adults - most of them being probably between 15 and 35 - age increasing, because the new generation will not stop playing games at a certain age. And if you start censoring games, were will you set a limit? Forbid books, that include criminal characters? Movies, like Oceans Eleven? Forbid Fairy Tales and Folk Songs? How many of them feature criminal heroes or violence and cruelty in general, which could be used as inspiration for crime? I have read the Scottish border ballads lately, and its just that computer games are more popular than the border ballads - otherwise there would be more burning-on stakes!

(as you may guess - I love the ballads AND the games)
