Hi everyone. I have been an avid player of the GT games since I had a psx. However I bought an X-Box and got into Forza but I have now got a PS2 as well so now it's back on with GT and what a difference compared to it's X-Box counterpart. I have a question though and that is what do the letters mean in the replays such as sm/sm, ss/ss ect. It's probably something really simple but my brain can't access it. It's Good to be back.
