The Romans are taking us about three times as long as we first expected. We thought we would have had them out by last August. Then December. Then March. Now we have no idea except we know we are more than 10 weeks out and probably double that.
We can always tell ourselves we will be making civs for the rest of our lives and/or that it will get quicker each time, but if we decide to go to 8, we need to decide who is 8th and need to decide that in a total vacuum. So we would choose the 8th while assuming there will be no 9th. If we ever have the luxury of revisiting that fatalistic view, then we will very happily and assuredly do so. But if we went to the Steppes for 8th, it would be unrealistic to leave room for a second civ from the exact same region that, if it ever came, would be be developed 12th or 14th or something, which would be more than a decade in real years from now. We need each civ to pack as much of a punch as possible if we are ever going keep momentum going for yet another one.
That’s precisely what I’m getting at. We can’t and shouldn’t expect a dozen more Civs, each one needs to be chosen very carefully.
