morrowind there is no single `best` title here for any player, each is better at something than someone else.
anyways.
to better income style for miner is making minerals by researching mining and getting as many clusters as u can hold onto. this method makes alot of money real fast and u can battle at any power rating range u wish given enough planets.
tacx miner is coming back also it seems due tot he current low food price. with this income style u just invest in housing research and get as much land as u can get ( U larges 8k+, 22k+ c2`s and such) this method makes ur base power rating go through the roof and will force you to fight at the multi millions to ensure any hope of a win but u can easily support miner fleets to the tens of millions and beyond if ur housing level is high enough and enough land.
the consumer goods miner is a decent way to make money but also makes the lowest amount of the three. invest in just industry reseach and get lots of land.
the fleet part comes from experiance and i usually never give out stacking tips as i feel its learnt thohrough practical experiance rather than what someone writes out for you to follow like have ship XXX in spot 3 to take out the usual XXX spams there and such...
practice makes perfect mate.
good luck
