I skipped a t297 DV, and I'm glad to have the CV as I really screwed some things up. The biggest mistake was forgetting about the Observatory - didn't build it until 220 due to drain bamage tech-wise.
I also did no RA's, which are probably quite helpful for a OCC!
I got all non-military wonders except Louvre, which again, I forgot about. After I built Neuschwanstein I forgot to build Walls/Castle as well. I slogged a natural GM all the way to Persia that I popped just after Internet - I had two more faith GMs on the way with a tile-busting convoy of 9 units to try to keep the path clear. I don't think I would have made it through Kathmandu a second time.
Full Tradition, Rat, Commerce, Aesthetics, 4 in Patronage, and 8 in Freedom. Policies came every 8 turns, I mostly began to quit caring what I chose. Ended with 121 happy, 121 fpt, 949 bpt, 264 gpt, 888 cpt, and 891 raw tourism - Cusco was pop 54.
I went Radio to Fertilizer to Plastics to Refrigeration (Hotels) to Internet to Radar (Airports) to Globalization (for DV fallback) towards Computers. Combustion TR bonus finally got me a TR to Darius on t299.
I passed Wonder Culture, then WI Freedom, then WR Taoism, so had 43/39 at first vote. Tithe gave me 109 gpt - I had the whole eastern 1/3 of the map converted, and with any effort could have had more than half. Cathy had Settlers backed up to settle my wastelands, which would have really propelled the spread because of Itin Preachers, but I just didn't want the nuisance of her surrounding me.
Poc kept asking me to join wars, but could absolutely never be bribed - I hate that part of the mechanic. Sweden and Mor were almost always willing to fight, and Sweden crushed IG while in 5 wars (2,697 hammers to my 770). He stayed with order amidst heavy pressure, everyone went Freedom after WI passed, except Poc flipped from Autocracy very quickly.
Darius forward settled Delhi, and lost Persepolis in a war. Sweden razed a Persian city too, and Poc took Moscow and another Russian city. Pretty wacky since there was so much warring, but the mtns really choked off troop movement.
I may try a regular game with these settings - it certainly was OP for The Inca, and it would be fun to see just how high the population could get!
