I can't tell you how many hours I have spent on all Sid Meier Civilization games ever since Civ 1. I have won every difficulty, every civilization, every victory type in Civilization Revolution on the iPad at least 5 times. If that type of draw that you can complete a victory in under 2 hours within an ever-changing world could translate to P2E, we could loop in another big segment of gamers.
So, I propose some flavor of a turn-based world domination strategy game in P2E powered by HG.
