Brady on O'Reilly Radar posted about Backseat Playground, a geolocation based game that tracks the location of a car and gives clues along the way for various mysteries and puzzles. (originally via Engadet who found it via The Raw Feed)
The research is sponsored by Microsoft and the Ordinance Survey, obviously both very large organizations that want to find commercial uses for their data/services.
Like the Come Out & Play festival, geolocation games can become much more common as devices come with Geolocation technology built-in, whether it be by GPS, WiFi, Cell, or whatever.
Are geolocated games the cure for the modern sloth of gaming? The Nintendo Wii already has gamers bowling in their living rooms.
Now if you can create great platforms for people to easily develop their own games, say by making waypoint, boundaries, rules, targets, objectives. And possibly use Splines/Blogjects to leave as markers, treasure, icons, etc. that users would carry around, pass off, leave, find, etc. Just wrap a nice story around it: buried treasure, Trouble with Tribbles, Pac-Man, Hunt the Wumpus etc. Really, you could probably take any old-skool game and make it into a really great geolocation game.
