I'd rather they keep adding to the roster and mechanics of Civ VI. I'm not in the mood to start over again. As far as mechanics go, I'm pretty satisfied with how VI is turning out. A new entry would only have less depth. As far as graphics go, I doubt they'd get much better objectively, and, subjectively, I'm fine with the aesthetic as it is. A third expansion? I'll take a fourth while you're at it.
