I see the point in "leftovers", but that doesn't rule out the experts. But then again, I'm not the one that has to program the damn thing
So, what experts do you have in mind? I see how taxes and food are in check for now and officers might be a bit advance, but the merchants, researchers and doctors seem like obvious choices to me. If you want to set up the game so that you're rewarded with a new expert for every 100 citizens you've gotta have some choices for what you want that expert to do, otherwise it's kinda pointless right?
