I tried v95 Japan, just 3 Godzilla cities that reached pop 51, 38, and 35. I planned to build a spaceship but didn't realize that since that VC is disabled, you can't build the Apollo Project. What I expected would happen is that I could build and launch the ship, but wouldn't get the victory screen. But the way it is makes more sense, given how Civ is designed. You wouldn't want the AIs building something that doesn't help them win.
I wasn't paying attention to the "no foreigners" VPs. I think it reached 182, dropped to 177, and then stayed there. I'm not sure what caused the points to increase or decrease.
I was very entertained that conquerors events seemed to be triggered unexpectedly (randomly) against European civs by my auto-exploring caravels long after I had first met the civs and scouted them with a scout. I got England (with my troops appearing in Iceland!), Sweden I think, and Portugal.
I passed 1001 VP on turn 568, 1898 AD.
Two turns later I finished Future Tech and every building and wonder I could except the Manhattan project, bringing VP to 1021.
The game can become pretty boring when it reaches the Industrial Era, especially if you're just teching. You're limited in how much you expand. The AIs expand anyway, and then usually collapse. The long turn times make it a grind.
The endgame gives you some things to do besides press enter, like maintain research agreements, influence city-states, participate in the world congress, and (if it matters) help or hinder other civs. Somehow, it's not really enough - not enough to make those turn times worth playing through, at least. However, it would be nice to see the things that give victories in the unmodded game - tourism influence, space race, world leader election - grant RFC VP. The game is designed for those things to be pursued.
I think occupying foreign capitals would be a good one, too - a certain number of VP per capital.
On the other hand, for civs that have RP points implemented, the game can usually end earlier, late renaissance / early industrial. It's not the worst thing in the world to leave the modern era as an afterthought, although it is unsatisfying, and I prefer long games that go all the way.
I have found that the early and mid game is the most fun for any civ, and military-oriented games like Vikingland and Germany were some of the most fun overall. Barb events make things interesting and generally seem well designed, like in the case of Greece where the events tell a story, and for other civs too.
I'm hoping to make another post where I review the late game buildings. Some of them come too late to make much difference, it seems.
