you just put all the things you want behind the only thing you do and money. and the thing you don't want(or who dosen't exist) behind thing that you don't want to do....
and why bounty hunting? why not mission? if someone is combat oriented but only want to do mission or combat zone? is he forced to play a bounty hunter too?
i just wrote 5 different ways to get upgrades. how did u get only money and combat ?
its not that hard..
more mining for mining upgrades
more trading for trading upgrades
more combat for weapons
more exploring for FSD upgrades
more smuggling for stealth upgrades
and money for the common elements upgrades between all these trades
its as simple as that..
