Money,taxes and caravans
Hello, I have noticed that when you buy at the market ... you can buy what you want, the money is not there "money". In the rise of nation (in which there are national borders) there are two ways to get money: tax the territories under its control or send caravans to their town or city allied. The idea would be to create the caravans (instead of the usual merchants normally used) to create "money" or "richness" with this wealth can buy the resources to market and build buildings.
If you listen to the community all you get is "more content = more better". It doesn't matter if it's a good idea or not, community polls will always result in that you add it. After that you'll get the @#$%ing in the forums about how unfun the mechanic is. You have to check if it fits your gameplay concept. If it doesn't you shouldn't implement it. If you let the community decide about gameplay related stuff you get a messed up game.
