12. Grand Theft Auto (series)
The Grand Theft Auto series, some think, will lead to the downfall of Western civilization. Why? Because you can cause mayhem in an open, slightly darker reflection of our own society. You can run over people in the streets, shoot passersby, or try to be a hit with the ladies. Kind of. The latest in the series, Grand Theft Auto IV, was a huge jump. A fully populated New York-like City with a ridiculous attention to detail. Maybe that's why people cringe when someone gets violent in Liberty City.
Gore factor: Zero to two pints of blood (varies). It's funny that one of the most controversial games ever made is also potentially among the least bloody. You read that right. Nobody forces you to go on a murderous rampage. You can just tool through the world if you want to goof around. But the point of these games is no more violent than award-winning thug films like Goodfellas and Reservoir Dogs. It's just odd that more people seem to get upset about the sexual parts of the game than any of the violence.
