i think it boils down to common sense,Rockstar should put san fierro,las venturas and surrounding countryside into the game because us (the consumers) know of such places and if we buy the game they arent on there well we will be pretty pissed off the game wont sell very well and rockstar should know that,unless they release those cities as extentions (like lost and damned and gay tony) someone has probably said this before.
but the question that is really on my mind is the radio stations,oh god the radio stations.
