For the past two days, I have had a blast playing Own This World on my Windows phone.
In the game you collect troops every 30 seconds in your geographic location in the real world. Using GPS tracking and your mobile internet (less than 5 mb of usage per day), the game uploads your stats to a central server where other users are competing against you for territory.
The fun comes in with battling other people who have laid claim to territory in your hometown.
Can you rule your world?
How powerful will you become?
