Slow work day so I set up a random game, became America, to try this lets all be friends and hug it out peace game again. Set some basic ground rules for myself -- no starting wars, no stealing workers from city-states, intercepting settlers (which would be war), if I attacked I'll just defend and push them back, I can liberate cities and I could raze cities if I was forward settled. But I was not to power up thru conquest. Went with Progress (+statecraft, +rationalism).
I was about 15 turns or so away from snagging the last religion. So I had to be happy with the one that Ottomans, closest neighbor got. Not good. No faith sinks what so ever. Had a hard time getting a good religion established for more then a turn or so, enough to build a faith building but not more.
I didn't manage to snag a lot of early wonders either, the last one I got was the Leaning tower. In total I got pyramids, sistine, forbidden and parthenon to. No time to be picky really. Build what was available. I lost a few wonder races by less then 10 turns. In the Industrial/modern era stage the Celts are currently leading with 15 wonders, they got most of those from Egypt after they took their capital. Venice has 10 and Siam has 6. What has happened now is just a shift in problem, happiness and tech are fine but culture is horrific. When I entered the industrial era I was already 2-3 policies behind to build any wonders, I lost Neuschwanstein by 7 turns -- as in I was about to get the last policy so I could rush it with an engineer with the Celts finally got around to build it in a non-core city -- yay
By that time I had waited -- as in had the tech but not the policy for two policies. At this point I think I can pretty much forget about wonders since while I can close the tech gap I will never be able to close the culture gap -- you can always regain tech but you can't regain lost culture. When the Celts picked an ideology everyone else was an entire policy tree behind.
I have managed to get 9 cities, 2 are horrific 1 tile-island that in the case of war I doubt I'll be able to hold. The Ottomans are constantly smack talking me and denouncing me, our capitals are only 11 tiles apart on a large map. Even when I'm at the unit cap of 50.
Besides that the game has been smooth, no happiness issues. Tech is fine. But as noted culture is a massive issue. I tried to spice it up since most of the game was just next-turn or checking trades and diplothings by agreeing to a defensive pact with the Celts. It was renewed once but so far no war. I think it saved me from a war declaration from the Ottomans. They bulked up along the border then just backed down.
So the judgement so far is that without Authority I have a lot of issues to gain enough culture which in turn prevents one from getting wonders which in turn makes it just worse by every passing turn. The Celts are three techs ahead at the moment, Siam two. I could close that gap. But I just won't ever be able to close the culture gap that will gain me any more wonders.
