actually you make some good points and I'm already at impossible for everything...and even so I make sure new systems are liberated only once I can't find new missions
I have an excel sheet with the game data for each mission (race who offers it, if you have to be a merchant/pirate/warrior to get it, etc etc)
I've done all the missions from the game menu, their not that hard once you do them once or twice
I even contacted some of the russian advanced forum players, I think only the code can answer this one
Anyway, thx for your help...always glad to see there's still a passionate following for this awesome game
