I just discovered that there is a french company that develops location-based games. It's called Recreator. The games are called navia and it seems that it's rather about using GPS and maps to play various games (tic-tac-toe, treasure hunt, conquest of virtual properties, tracking people or finding a specific place with cues). They have relevant partners like IGN (the state-owned geographical company that takes care of all the maps and cartographical stuff).

Why do I blog this? I like this sort of "alternate reality games", it's very interesting to see what you can do to entertain people with just a map and a GPS.
