I remember during my first replay of GTA IV, at some point I thought "Damn, I didn't learn this map at all, what the hell is the matter with me. Guess I'm getting old." Eventually it dawned on me that it was because of the GPS route feature, always leading me exactly where I needed to go, no effort required from me at all. I turned it off and it's been off ever since. For me one of the funnest things about GTA has always been learning the lay of land to the point where I can navigate through the entire game as if I'm driving around the real city I live in. And GTA V is going to be extra sweet, being an LA native. First thing I'm going to do is turn off the GPS route. (I'll save turning off markers for a replay.)
