Hello Brygge and welcome to the forum!
Now I have to answer... because what you wrote is not correct. That's not a bad thing because - if you haven't become mayor in P2 yet - you're not that familiar with P2 yet. In any case, it's nice that you're trying to help!
In fact, becoming mayor isn't as hard as you write. Even a beginner should be able to do this in 1 year. Simply trade, build ships (or board them by the pirates - escort orders! ). Your reputation increases quickly and you can stand for election. The quickest way to do it is in our tip collection - which unfortunately is only available in German. But maybe you can hunt individual passages through the translator...
The pdf you attached also includes prices (purchase, sale). I hope the sales prices are not your standard. The profit would be quite high, but that wouldn't make your population happy/satisfied. But that is exactly the key to success...
Good supply of cities -> population becomes satisfied/happy -> population grows -> more goods are needed ( -> construction of businesses) -> supply of cities...
Pirate ships are free. Accept an escort and a ship yourself (Kraier or cog, fully manned and equipped with cutlasses, if there are only a few there like at the start of the game, they are enough for now). As a beginner you can board 5 ships per month. With a little practice it will be well over 10 per month. Our “cracks” managed 1 ship a day. Please do not destroy them, the ships will sail for you later. You can board it without firing a shot
This requires a captain with a combat level of 3 or higher (and perhaps a good sailing level). As a result, fewer of our own sailors die.
There is information about the sales prices in the tip collection under Tips and Tricks, please take a look there. Basic supplies such as beer, fish, grain, wood are usually resold at the cost of production - or less (grain, among other things, has a manufacturing penalty in winter and therefore becomes more expensive).
The goods that bring money are hardware, furs, wine and cloth. Yes, spices too, but the quantities that can be sold profitably are tiny.
The stupid thing about P2 is that, as far as I know, it's not available in English... which is why P3 is probably the better game variant for English speakers.
I hope you enjoy playing and if you have any questions, please write in here when you play P2. Although the game mechanics are supposed to be the same.
Best regards
