Geolocation

, or "location-based", means the game localizes play based on a player's actual physical location. DoS is such a game, providing a player's exact position (Americas, Asia, Europe or Other) via the GPS or location service in the PlayStation.

In DoS, the only ways to gain spirits from new areas is to either physically travel to another place, at which time the location function will alter to the player's new position, or to trade spirits with players in other geographical areas.
