What would you add / change to make the game fun and enjoyable which would make you the player want to open and play it constantly?
I'm not player of this kind of game however I know how this game is played. My major gripe with people aspiring to make such game is they never specify the goal which is important. For your concept, you mention becoming leader of community which unfortunately not quite clear.
So my suggestions are :
1. Specify in detail the goal of the game. Ex: Leader of community, specify how big the community should be, what the community should have to be called thriving.
2. Make alternate goals which alter gameplay. Ex: find hidden spring and construct structure to share the water from the spring. Or construct settlement for people living in distant places.
