Korea is good wide though because you can build a university, public school, research lab, factory, workshop, bank, stock exchange, and possibly even a windmill in 4-5 more cities. Working all those extra specialist slots banks you 20 extra science on top of the extra science you already get from universities, public schools, and research labs. That's what I mean by more specialists, you can max out the capital to have the 6 guild buildings but not the other 10 specialist slots possible per city. You can get windmills too, making it even better.
