Can you create a new kind of Ore (price 30000 c/unit) , and put that in only one system , so players can establish new bases, everyone ll come there to mine , it ll create new popular destination in game
also 3 or 4 pirates bases around that field , so miners ll need escort to mine and for transports
also make that Ore very low Density to be hard to mine , put big asteroids so ships can hide behind it
and finally we need new Miner ship, thin armour , with big bonuses for new kind of ore , so mining without escort ships will be very dangerous
simple way to boost interactions between players in a game
