There's alot of realestate on the map, its unlikely it'll ever all get claimed. Was it @jedi_warrior who suggested a timer? That's a great idea for ownership, if a player hasn't been back to the game for say a week their claim is given up. Last thing we want is to have servers full of claimed buildings with non existant players.
The question I have now is how do we differentiate claims? How would we know which building belogns to whom? Would there be one trophy for all players or a different trophy for every individual player. The latter might be hard to achieve, I think. What are your thoughts?
