Need for Speed VS Gran Turismo

One of the biggest rivalries, taking place between Need for speed and Gran turismo(both excelent racing games). Starting off i'd like to say that Need for speed is a game for the tuners it's based on tuning your car, and less on racing. But, Gran turismo is a game that is a racing heaven, a wide variety of cars to choose from. Even though lots of people prefer NFS, GT is still a very good racing game. They also give names to each games like "Arcade mode" for NFS and "Racing Simulator" for GT.
