Player Vs Player

We are planning to have player vs player combat close to beta version, in that scenario players can see bases made by other players and cannot make a base in the range of 200 meters of other player base, having you to combat for space. Because of lots of players are playing on a planet than space will be a problem, and you have to destroy any player base to make in that 200 meters of area. However once a player has bought a planet or conquered it. Then owners bases cannot be destroyed. Players have to pay a certain rent charges to create their bases or fight regularly with the planets droids army that always try to assert the power of planets owner.
