Modification has been encouraged in GTA wherever it has been possible especially in terms of physical appearance, clothes and choice of ride, so it’s not beyond the realms of possibility for this to be shared between users online. Then Rockstar themselves could add more cars, clothes weapons to keep the experience ever expanding.

Will you able to flaunt the law so freely? Or will this be a much more serious and uptight experience than before?
