The content of the game, from glorified drug peddling to gang wars, was ripe with controversy; Take Two has enough controversy (Hot Coffee, Oblivion, and Bully) to deal with right now. Bully, in fact, has not been mentioned by Rockstar since December of 2005, yet has become a staple example of the "horrible games industry" by certain anti-game activists.
