I would conquer a port and want to upgrade everything so I could protect it and get the maximum trade discount but the taxes would be too great and I'd have to sell it off. Does anyone know of a basic strategy for taking over ports. I read some strategy guides online but no one dealt with the tax issue. There has to be a ship to port to profit ratio rule of thumb to keep in mind but it seemed easier to me to not own ports and then the year before the game told me I had to have 5 ports if I wanted to continue I would hury up and conquer some and then sell them off after the year was over... ha! it felt like cheating and if I am going to go to the trouble of playing a game to dominate the world it would be nice to have a plan of attack... of course I am writing this after playing the game for 72 hours on 8 hours of sleep.
