Grand Theft Auto is the third in a very popular and controversial series of games.  The games are often criticized for their strong violence and aggressive nature.  Rockstar Games has successfully taken the series to a new level with their first fully 3D environment.  Some of the first things to jump out at you while playing the game are the new visual style, lots of cars to drive, tons of new sounds and music, an even higher level of violence, and an open-ended style of gameplay that is unprecedented.
