Once you build some production structures for refugees, you can employ them to harvest various resources. Your settlers will gain talent in a rogue-like style (similar to Ludus Master). However, each even level, they will also gain one vice - for example, they will eat or drink more or demand some services. If these requests are not met, they may leave your settlement. Each sixth level, they will demand one luxury item (like cakes or mead). As a production of these items will not be implemented in the next version yet, there will be a level cap of 5 in the next version (it will be lifted in following version).
I want to make this system easy, so there will not be too much hustle to manage your settlers and their demands. As I see it, the goal of this game is to have fun and see some sexy situations, so the management part will not be too demanding. It will be there mostly to test this new features and provide new situations for a player to explore.
