I think that you should add some achievements and that there should be more celebrations for population. I also think you should be able to call the Court of Crowns (or what ever its called) and be able to ask for money is you are in debt, need to get rid of spirits, or need something else. of coarse if you did this to much the I think that the should deny you until you help some one out
some charterers I think you should add are
- robber - this guy would come and steal a medium sum of your money randomly/ when you get too rich
-killer - this person should come to your town randomly and kill some of your population
-police - puts robbers/ killers in jail
-3 little sheep - these are a group of sheep that come ask you for materials to build there houses (one asks for weak stuff, one asks for medium strong stuff, and one asks for strong stuff)
- big bad nice wolf - this character would come and ask you things like "have you seen any sheep lately" "do you have a strong fan of some sort"
thats all the ideas i have now
