Three Moves Ahead 462: Sid Meier's Civilization VI: Gathering Storm

The seas are rising. The air is getting worse. Rock bands are forming. Fraser, Sean Sands, and Troy "The Diplomatic Juggernaut" Goodfellow go for Just One More Turn (tm) with Civilization VI: Gathering Storm. In this, the "second Civ expansion that finally finishes the game", the player fights against other civilizations as well as an increasingly hostile Mother Earth. Gathering Storm is a worthy addition to the series, but where do we go from here? Certainly not beyond earth (cough), but with Civ as a whole?
