Pursued is a great geography game that uses Google maps. You’ve been abducted; but, now you have escaped your abductee. You can phone a rescuer but you must be able to tell the rescuer where you are. At each of the 16 levels you are “dropped” in a new location and you have to use landmarks to figure out where you’ve been dropped within a certain timeframe. Finally, you can create your own levels using Google maps as well.
I have to admit, it’s somewhat addicting. Enjoy
