There are no microtransactions whatsoever. Never have been any from all my time playing it... a few years.
The game is social, if you have the drive, ambition and charisma, you can become Monarch/Dictator/Presidente.
Top 4 Positions
Monarch/Dictator/Presidente
Judge
General
Banker
Those are the top 4 positions of a kingdom. Kingdom laws determine how those positions are chosen.
Monarch/Dictator is elected once and is the boss for life. Whenever the boss is disposed of, a new election pops up for the next boss.
Presidente is elected every month.
Judge/General/Banker can be chosen by election every month or be appointed by Monarch/Dictator/Presidente.
Other positions...
Sponsor: The financial backer of an Army. Usually a Duke/Lord/Lady sponsors an army since they have income.
Marshall: Leader of an army. Chosen by the Sponsor.
Sub-Marshall: Second in command of the army. Chosen by the Sponsor
Duke: Own and manage a city. Very high income, but also greater responsibility... the city people require food that you have to buy from the Lords/Ladies... or foreigners. Needs some knights, I think 1 is enough. (Usually a for life position...)
Lord/Lady: Own and manage a province/town... income/food production ranges. At least 1 knight is needed to properly manage the province/town. (Usually a for life position...)
Knight: Has an estate in one of the provinces/towns/cities. With that, your source of income is from that province. Can be assigned into an army by the master they have sworn fealty to.
Noble: Unlanded nobles. You don't really have much of an income... Find a Lord/Lady/Duke willing to provide an estate to you.
Adventure: A commoner or bastard. Hunt monsters and undead. Adventure. Loot unique items. Get thrown into prison by ornery +noble.
How elections can work.
1) Everyone has an equal vote.
2) Everyone can vote, the votes of Lords/Ladies/Dukes count for more.
3) Only Lords/Ladies/Dukes can vote.
