Most important, buildings affect events. You are less likely to get rebellion where you have herbalists and teathres than in underdeveloped town, even under low stability. Food from farm also helps. Also taverns and inns attract merchenaries and travelers, and even spies, and cities with dungeons quell dissenters better, as well as handle crooks.
Buildings that need to be present in every city have 3 levels: either they are present in every city, so that you get full benefit, or they are present in at least half cities, but not in every one, so you get half of their benefit, or they are present in less than one half of your cities, so you gain no benefit at all.
This is to make an incentive to keep down the number of cities and make a strategic decision – do I need one more city, to get extra commerce, or I'm better of small or more stable, so I'll put up a outpost or fort? This will also, I hope, encourage forts and outposts, and add more diversity, and also make it easier for me to keep track of all provinces
Techs and tech requirements latter on.
