Everything from the excessive promotion of violence to prostitution--so many parents, politicians and political pundits were pissed off. The games are clearly not for children, hence the rating M for Mature. But parents still bought the game for young kids and were shocked that the game wasn't for kids! Oh, noes! Players can drink and drive, kill anyone, steal cars, sell drugs, bang prostitutes (then kill them) and antagonize the police.
Each game takes place in a new, fictional city based on actual US cities (San Andreas is based on Los Angeles, Vice City is based on Miami, etc.) and a new protagonist for each game. Each protagonist has one thing in common, though: a life of gang or mafia-related crime. The purpose of each game is to rise to the top of their respective crime worlds and to do this, you have to get your hands real dirty. With every GTA release, Rockstar Games becomes embroiled in another legal battle. Sex, cars, crime and the ability to commit almost any type of violent act you want left critics steaming mad. And they get madder with each release.
