(but I no longer have houses in city, so coins production took a big hit).
I wouldn't remove residences until I've got enough SoK/SSW for coin. Just a few give a lot so it doesnt take long.
I heard it was Chinese or Japenese, I'm not sure which. But Hungarian ranks among the top most difficult ones, too. Which is not surprising. When someone learns all the grammar rules, the rules get changed.
I'd guess from Chinese it would be Mandarin - much more difficult than Cantonese although I guess fewer people speak Cantonese..?
Russian has the same issue of grammar flipping out once you get it. There are exceptions to the rules and then exceptions to those exceptions. And then there are standalone rules too :p That's why I speak street better than grammatically correct.
I bet this language is among easiest to learn.
I find Romanian is the easiest language I know so far. I was conversing with native speaking strangers within a month and a half and they were surprised id been speaking such a short time. It's spoken and read exactly the way it's written and there are no exceptions or gender distinctions or any other complications. The only difference is that c sounds like ch and ch sounds like c (k) :p
