>I always thought that it was my innate ability to navigate three-dimensional spaces, but now I begin to suspect that this is a trained "module". I walk a lot (mostly in cities), and I played first-person shooters since the first DOOM back in 1993. And I recently found out that I strongly prefer first-person games to top-down / 2D games -- I instantly feel "at home" there. For me it was MUDs, exploring and running to known locations in MUDs almost certainly developed that feature in me as I was playing then in 1994 when I was all of 9 years old and my sole means of transportation was my bicycle in the real world.
