Good missions change the complexity of passing a mission linearly, and not spasmodically. At a very easy level of complexity, it is necessary to play easily even for a beginner. There must always be enough resources so that the famine does not start, or gunpowder, iron, gold do not end. Informativeness about the mission's goals and ways to achieve them should also depend on the level of complexity. Cossacks are an economic strategy. Do not forget that the amount of resources that the player receives at the beginning of the mission and after performing the current tasks will greatly affect the complexity of the passage of the mission.
