On a related note, playing far cry 2 without using the handheld map and walking everywhere did wonders for my spatial memory. The game is gorgeous and full of tiny details so it isn't as boring as it might sound.

Each mission starts with an npc giving you the location of your target (safehouse 2 miles east of shanty town, outpost south of lumber yard). Sun can be used as a compass (when it's not raining). After a while you start to recognize the landmarks and don't need the map anymore.
