In each sector there are areas with empty planets and comet-clouds , planets have same resources as your planet , clouds have 1-2 types of resources . i was planning that each player can build a special type of ship and send it to that area with the planet/cloud and start mining there , but he would need another ships to defend that area from other players/pirates

only one player can mine a planet/cloud , means ur friends and allies won't be able to sneak in and mine with ur protection there . to be able to mine you should destroy the base on that empty planet/cloud and build urs using that special ship
