I have been thinking about how to describe VP to a friend who knows CiV. "So, they changed the civ properties. And the social policies and trees. And the tech tree. And how city state diplomacy works. And the units, oh and the promotions too. Also all pantheons and believes and most wonders. There are events now and you can have monopolies and corporations and..." Ok this aproach wont work. Maybe I should just say what parts stayed the same. All right. "...." Well. So here is the challenge: Define the most significant item (I kept it vague on purpose, but be more precise than "You build cities and discover techs") that remained unchanged from vanilla CiV. The winner gets to define how it will be changed.
