My route-memory and navigation have been trained by my time spent playing games. It takes me between one and three trips to a new location before I've memorized how to get there, since that's about how long I would spend getting owned on new FPS maps before I figured out where all the important stuff was. Similarly, I can fill in route gaps if I'm in an area I don't really know, but know where I want to get. And if both of those fail, it's just plain handy to be able to read a map when I'm lost thanks to games using so many of them. Minus the convenient, constantly updating, "You are here" character marker.
I guess I could just get a GPS, but I suppose I enjoy doing some things the old fashion way.
