More and more games and prepared behind computers without visiting the actual place.
Loquic game generator uses OpenStreetMap and Google Maps /Satellite photos. If you care to import your locations using KML files, you can even use Google Earth and whatever local mapping services for placing locations.
Today Google announced StreetView rollout in several new cities. Making games became easier again 🙂
It seems that more games are made using StreetView (Google) and Birdview (Microsoft) than good old visit the place 🙂
