From what I read the player should replace the cottages with workshops when the right techs/civics are researched. I understand production-wise the workshops are great (obviously) and they can give gold too, but how they can compensate for the lost research? I may make a mistake but isn't the commerce research multiplication much higher then the research which can be produced through the workshops?
Also later in the game the AI changes everything into windmills. And there comes the same question - the windmills are better food-wise but what about the research?
