Since I haven't played the game yet I am wondering does Beyond Earth have happiness or some equivalent? Are there some resources that need to be acquired to maintain your population? Does anyone have a list of the resources and what they do? What is the function of each resource? what units they allow you to build and how they relate to affinities? I am sure some may add a hammer or food to your tiles. Are there any that are considered OP like salt? This knowledge will allow us to hit the ground running.
