Need reasons to sign? Reason #1 If/When Gran Turismo 6 servers shut down, you will no longer be able to use ANY user created tracks. Reason #2 You can no longer have free run lobbies. GT Sport basically limits you to play like GT 6 quick match events. Many people (Including me) do not want to race like this. Reason #3 MAJOR lack of production model cars in Sport. That's not a problem with GT 6. Reason #4 The game is only 4 years old. GT 7 is no where in sight. Sport isn't for everyone. So why force people to it? There are games that are 10 years old that are still online. There's no reason for GT 6 to shut down before a proper sequel is even out.
