I settled in place due to the river placement (which is hard to see in the Announcement screenshot). The only other two starting spots which seemed like they had potential were the two hills to the SW and SE. The SE one loses out on the river and the SW one gains the hill but wastes the extra food from the deer.
POLICY:
Full Tradition, Full Piety, Full Patronage, Commerce opener (not yet in Industrial), Full Freedom, rest of Commerce, Honor opener (while building Utopia).
I wonder whether I should have opened Piety and gotten Mandate of Heaven before finishing up Tradition, but the growth bonuses really helped.
Unfortunately I didn't get to the Industrial era fast enough so I opened up Commerce before accessing Freedom. If I timed it better, my game could have been a bit faster.
Alternatively, maybe I should have saved the Oracle (since the AI doesn't usually prioritize it) until Freedom was ready but I was worried about someone snatching it. Plus, it helped me complete Piety sooner.
RELIGION:
Religion played a major factor for my game. As an inherent Wonder Whore, I went for a high production focus, choosing:
Pantheon: God of the Sea
1st GP: Tithe
1st GP: Religious Community
2nd GP: Cathedrals
2nd GP: Messiah (cheaper Prophets)
Ethiopia was the first to Pantheon, I was the second. But I got my religion enhanced before anyone even founded another religion. Eventually all the religions were founded but it took a long time.
I tried World Church in the last Cultural GOTM (#41 with Byzantium) and wasn't too impressed with it so I went with the ever reliable Tithe instead. Usually I have better things to spend my Faith on than missionaries, but it actually might have worked decently in OCC, especially if combined with Great Mosque + Holy Order (cheaper missionaries).
I also considered Divine Inspiration but decided that the extra Great Artist slot from the Cathedral was worth it.
I eventually spread my religion to China, Egypt, Persia, and the Huns. Never got around to spreading it to Siam.
After me and Ethiopia, the others to get religion were Egypt, Japan, and Persia. (This partly displaced my religion in Egypt though most of Persia still kept my religion).
EARLY TECH / BUILD:
Pottery -> Sailing (for God of the Sea) -> Calendar (from Ruins) -> Writing -> Archery -> Animal Husbandry -> Trapping -> The Wheel
Scout -> Monument -> Granary -> Stonehenge -> Temple of Artemis (those two wonders for the Great Engineer points, since I was going production happy)
In terms of overall technology:
I almost missed out on the Statue of Zeus since I didn't have Bronze Working ready (but rushed the tech and the wonder).
I did accidentally enter the Renaissance when I didn't plan to. I wanted to pre-research Acoustics and forgot to change it when it was at 1 turn away. I did prioritize Architecture (for Hermitage) - it's weird because I'm still used to its older Vanilla placement.
I didn't get to Industrial fast enough for my next social policy. I probably should have used Oxford or burned my slacking Great Scientist to reach Industrial sooner but I was worried I might need them in the end (which I didn't).
I ignored Military Science until too late since I was focused on possibly needing to reach Ecology. As a result, I didn't have enough remaining time to build Brandenburg which really would have helped!
In the end, I was firmly in Modern Era with: Refridgeration (those oil platforms helped!), Plastics (from Oxford), Replaceable Parts, Flight, and then one turn away from Railroad.

Only wonders that other civs got were Petra (Egypt) since I had no desert and Machu Picchu (Persia) since I had no mountain.
Focused on Engineer wonders initially.
Regarding the Ancient Wonders DLC: Being able to get the Temple of Artemis was very nice. It helped make my capital big. However, I probably did non-optimal build orders to get Statue of Zeus and the Mausoleum, just to prevent the AI's from getting them. I probably would have been "faster" if I had ignored these two wonders.
Another player mentioned using the GL for an early Drama & Poetry for the extra Amphitheater culture (free from Legalism). Maybe I should have done this. I ended up using it to enter Medieval with Guilds.
After building SH and ToA, I had finally met most of the other civs. Between scouting out their capitals and paying 25 gold for embassies, I noticed that both Egypt and Ethiopia were building the Statue of Zeus, and I hadn't even researched Bronze Working yet (was halfway through Mathematics). Even though I didn't need the Statue, my wonder whoring nature meant that I had to go for it. Quickly researched BW and then prioritized production, beating both of them to it. Kind of non-optimal since it didn't help me, but I gotta get them all!
After that, Ethopia started working on the Great Library, but I easily beat him to it. Similarly, I also built the Pyramids and the Mausoleum far earlier than I would have wanted, to prevent Egypt from building them. Ideally, I should have built the National College before the Pyramids, but I wanted to beat Egypt so I did the Pyramids first.
Being a culture game, I did prioritize cultural wonders like Terracotta Army, even though I was itching to build Great Lighthouse and Colossus first! Similarly, I prioritized Sistine Chapel, Alhambra, Taj Mahal, and Louvre.
I was saving Hagia Sophia for later to reduce the cost increase of Great Prophets and almost lost it to Persia as a result. Fortunately, my traveling spy spotted Persepolis building it at 4 turns away and I hadn't even started! Switched production and it was at 4 turns, played around with tile selection to get it to a 3 turn build time, which beat Persia. I was also a bit complacent with Angkor Wat and Notre Dame and probably should have built them sooner (tech stealing AI's can cover a lot of ground!).
I saved the GP popping wonders (Leaning Tower, Louvre, Porcelein Tower) to all go off around the same time in order to generate as many normal Great People as possible.
In the end, not enough time to build the Eiffel Tower or Cristo Redentor. I did have a spare GE (in addition to the one used for the Statue of Liberty) but thought it would be faster to settle for extra Utopia Hammers. Also, if I had researched Military Science earlier, I could have gotten Brandenburg. Darn.
In terms of National Wonders, I probably should have built Oxford a lot sooner. And I forgot about how helpful the National Treasury was so I didn't do that until the very end. It was nice being able to build National Wonders in just 1 or 2 turns! One of the few perks of OCC.
For once, I actually managed to get overflow to work! Did: Armory -> Arsenal (pre-built to 1 turn) -> Stock Exchange (pre-built to 1 turn) -> Statue of Liberty (GE to 1 turn) -> Utopia. Normally Utopia would have taken 10 turns with my fixed tiles and production focus, but got it to 8 turns due to overflow and then after unlocking my tiles and playing with specialists (due to Statue of Liberty) got Utopia built in just 7 turns.
GREAT PEOPLE:
Besides the two Great Prophets for my religion, I also settled 4 Prophets by the end of the game. Settled 3 Engineers and used one (from Educated Elite) for the Statue of Liberty. Used 2 Great Scientists for bulbing. Only settled 4 Great Artists but I used a bunch for Golden Ages (also bought 3 of them with Faith). Got 1 Great Merchant (Educated Elite) which I settled and then in the final turn I bought one more. 1 Great General generated normally, 1 Great Admiral from Educated Elite.
Educated Elite: Merchant (crappy), Admiral (crappy), Engineer (good!)
Faith: 5 Prophets, 3 Artists, 1 Merchant
Wonders: 1 Scientist (Porcelein Tower), 3 Artists (Louvre + Leaning Tower), 1 Prophet (Hagia Sophia)
Normally: 3 Engineers, 1 Scientist, a bunch of Artists
By the time I built the Taj Mahal, I was in a near constant Golden Age, though I did miss a turn in between (wasn't paying attention) which was annoying. Need to pay better attention.
Was pretty good assigning specialists, though after I rush bought my museum I forgot to assign specialists for a few turns.
Should have gotten an earlier Great Prophet instead of spending it on a Missionary (after Great Mosque).
I probably should have settled my 2 Great Scientists. They were costing me maintenance and didn't actually help bulb anything useful at the end.
For Leaning Tower I chose a Great Artist, but it probably should have been an Engineer instead. The extra artist didn't help out that much.
Should really have built Brandenburg to get that extra Great General! That would have let me get the coal I needed to build a Factory, which would have shaved a turn or two off of Utopia.
SPYING:
Wasn't that useful. I didn't mind other civs stealing from me to keep up but that didn't help. RA's were still too expensive and no one could access coal.
My main use for spying was sharing intrigue to bolster my diplomacy.
A well placed spy did tip me off about Persia building Hagia Sophia in time for me to get there first. They also gave me heads-up on Angkor Wat and Notre Dame.
DIPLOMACY:
Prioritized the Cultural City States and spent most of the game allied with them. Gradually allied with all the other City States until I had them all by the end. This sucked up most of my gold and I didn't have much for Research Agreements or to rush buy too many buildings (though rush buying felt really wasteful when I could build anything I wanted in just 1-3 turns).
One early RA with Siam, and then in the end game I had 6 RA's go off with 6 different AI's before the game ended.
Never got in a war. Spend most of the game gaining XP with barbarians. Other than my initial Warrior, a Scout (upgraded to Archer), a Trireme, and 2 or 3 rushed Archers, never built any military units. But my CS alliances meant that I was awash in military units. Was usually in the top for military, securing the top when I bothered to upgrade. There were several times when CS gifts resulted in exceeding my supply limit so I had to gift units away (which I normally never do). I probably should have gifted even more to save on maintenance, since I didn't need all those units. However, it did mean that my capital was usually awash in units, so I never had to worry about enemy Great Prophets sneaking through.
By the end of the game, was friends with 6 of the AI's (only Ethiopia was standoffishly Neutral). Siam was quick to befriend me in the beginning and we were friends all game long (though near the end he was getting annoyed that I was friends with his enemies). Japan and then later the Huns seemed to be the main pariahs of the international community. After saving a Japanese settler and worker, Japan offered friendship but I initially turned it down due to the diplomatic consequences. I gave some money to China which was enough for her to offer Friendship. Egypt and Ethiopia didn't like me due to wonder coveting and city state jealously. It took a lot of effort to get Egypt to like me (rescue his worker, give him gold, share my religion) but that's due to Egypt's AI programming (like Elizabeth) and he eventually offered his friendship. After that point, I finally accepted Japan's friendship offer. Needed to give Persia gold and share my religion to get him to DoF. Near the middle end game also made friends with Attila (it was easier than I expected, considering that I was friends with several of his enemies). Could never get Haile to like me enough though.
Someone mentioned that warring has little purpose (other than for gold) in OCC. I disagree. You can eliminate rivals (who might compete for wonders on higher levels) and improve diplomatic relations with others. Also, you can generate XP for Great Generals. In hindsight, I should have warred with Ethiopia, to generate an extra Great General or two.

from camps), World Church (+
from other civs), Cathedrals, Feed the world (+
and I lost that ally for a few turns. Otherwise it was a very interesting game strategy-wise (lots of decisions to make), but not very eventful. That's how most cultural victories are. With all the militaristic city-state allies I had, I really wanted to DoW someone, but I just didn't have it in me.
. Nobody knew how to get the damn coal. not the civs, and not the city states for some reason, even if they were gifting me machine guns...
sooner to get the wltk-growth going. 
2 water oil spots were welcome addition.
