when to build what?

[This World is an illusion, exile]

im strugling to understand the priorities and timings to build buildings. for example i dont get when do i need to build more military buildings even if theyre duplicating already, or when should i build less infrastructure buildings etc. as i understand there should be some sort of a pattern for this

In depth it depends heavily on the race and faction. The common rule maybe being the money making building as a priority most of the time except when you really need access to different units, but alas then you could be playing vampire coast which 99% of their settlements building are a total waste unless you are Luthor and you are oblige by campaign goal xD Ask for a specific faction tips better i guess.

I tend to prefer making my starting province focused on recruitment buildings, and thus where I raise new armies and them make every other province income focused.

If buildings give hero capacity then it is typically worth building those in every major settlement.

Unless you are playing as Nurgle or Tomb Kings then in those cases you will want as many recruitment buildings due to their unique style.
