This is a Locative Mobile Phone Game (LMPG). A game for iPhone and Android, which uses either GPS or the My Location feature of Google Maps on the iPhone:
“According to its description, Parallel Kingdom places the virtual world on top of the real world using the GPS inside your phone. You can attack, dance, hug or team up with anyone around you. Set up trade routes, craft items or even create your own kingdom.
You can mine resources, build buildings, craft items, trade goods, meet people, start kingdoms, lead wars, and explore the world. Wherever you are, you can open your phone and play, whether you’re on the bus, walking down the street, or at home. Anywhere in the world, any time of the day. Parallel Kingdom never stops, you play it when you want and where you are.”

Pocketgamer.co.uk published an interview with the CEO of Parallel Kingdom, Justin Beck:
Pocketgamer: How do the GPS aspects work? How are you tackling the problem that people might not be within range of anyone else who owns the game?
Justin Beck: We want to find some balance between leveraging the location game play of Parallel Kingdom without forcing players to move to do every little thing, which could get annoying quickly.
The GPS controls what part of a neighbourhood you are in and from that location you can then move your character within a couple block radius of your actual location. Giving you the freedom to explore while still being completely location based.”
