Ok, sorry to be asking what i think is a stupid question but im lost as to what the difference is. I have GTR Evolution, bought as the DVD wich includes Race07. I have the touring cars wich i believe is the original race07, some caterhams that is a addon i think? and the GT cars and nordschelfieifiefieifefef track wich is the GTR Evo part. What is STCC? is this another addon that i can get, or a different game? Just asking because i keep seeing STCC mentioned and one of the club races seems to list the cars i have but says you would need STCC to play. Thanks in advance for spending time reading the ramblings of a mad man.
