This is neat!! I'm still learning the game, but fwiw I definitely feel that cities not having a rest action is a major friction point. I'm currently in a long period of peace and exploration, but I can't rapidly skip ahead because my 2 towns have to keep switching the same hex back and forth between
mine and forest (can't build anything else).
Another question: is there any way to control your standing with other civs? Seems like if you are peaceful, that is that, and there is no way to change it. But maybe I'm missing something.
