I for one would appreciate having the “etc” bit expanded upon. I have never been able to figure out the peaceful CV path. I understand the general outline, but I can never seem to get those mid-game cultural wonders, and timing/winning International Games never seems to be something I can manipulate. The game elements I can easily control never seem to amount to nearly enough.
Hmmm I'll do my best. Well following Acken's recommendation the Peaceful Cultural Victory requires your civ to do a lot of heavy lifting in the mid game. After all that is when most of the cultural wonders and archaeological digsites become available.
As far as wonders go my priorities sorta go like this
Sistine Chapel (essential) - basically an extra museum and the +25% culture does 2 things. Firstly it prevents another civ getting it which stops them getting an enormous cultural boost (which slows your tourism and is a nightmare to deal with for Civs that are competing on Culture Victories or have a tonne of cities). Secondly it helps with social policies - Cultural Victory is the hardest because you'll need Rationalism + Aesthetics.
Globe Theatre (I don't bother with this one)
Uffizi (only if I miss Sistine Chapel)
Louvre (very desirable despite the point in Exploration)
Eiffel Tower (essential)
Broadway (there's 2 ways to go about this - either you save all your Great Musicians to do a big concert bomb at the end or you build 2 & theme with this wonder then hold off any more musicians until the end. Either way I don't mind this Wonder the theming bonus is quite strong.
Getting Archaeology early is also important as you can plant scouts and other units on digsites (even in other civs territory) until you are ready to dig them. You can dig a maximum of 1 site without incurring any diplomatic wrath from the AI. You can also turn a digsite into a landmark in their territory for a permanent diplomatic boost. This can be quite helpful if there is a civ that has a number of reasons to dislike you or attack you - eg opposing ideology. Maintaining peace for a peaceful culture victory is important if you want to keep a diplomat in their capital, trade route going and open borders...
If you do well here you have successfully laid the foundations to win a culture victory - you'll have a few culture wonders with theming bonuses, some great works to fill your museums and some landmarks around your cities.
From there you want to bulb/research your way to the techs that amplify your tourism. Refrigeration for Hotels and then to Internet. Radar is also a tech to consider as the Airport helps with tourism.
So how to get these Wonders? This map presents some major difficulties but also some opportunities. Firstly I'd move your settler a couple tiles North so you are within 10 tiles of Constantinople. This almost guarantees that you will get an early trade route from Byzantium and you can send one to them. This should generate you 6 beakers per turn in the early game which is significant.
Don't try to declare war on Byzantium to steal workers, get one from Hanoi instead.
Build order should be scout, scout, shrine, monument (if no culture ruin), caravan (to Constantinople), archer, watermill/granary.....
Make sure 1 scout goes North before Constantinople claims all the land blocking you from getting though - you need to meet as many civs as possible to get research bonuses.
Your strategy here will avoid building early settlers. Basically because a culture victory is so dependent on mid game strength (based on a strong capital) building settlers early is just too much of a drag on your capital. Sell your luxuries and resources to get to 500 gold to buy your first settler - if you're lucky you'll get an early offer of friendship from Theodora. After you get Petra & National College build more settlers.
My tech order would be to beeline Currency to get Petra asap. It is such a strong wonder that the earlier you get it your civ will be much stronger. If barbs are a real problem then building a war chariot will help a lot. You can decide if you want to get Hanging Gardens in the meantime. It's risky but you might be able to do it <check what civs are playing Tradition and try and get an embassy in their capitals. If their building it you can declare war on them and that may change their build priority.
After Petra get your National College out, new cities planted, run food caravans to the capital and aim for Civil Service ASAP - your capital will grow like crazy at this point. You've got nearby Cultural and Maritime CityStates so do all you can to ally them as the culture and food bonuses are also very important.
Get to universities asap and then immediately aim for Acoustics. After Sistine Chapel you can either tech to Architecture or go back and aim for Metal Casting and Printing Press/Leaning Tower as you choose.
But basically at this point you want your cities to be working universities to build Great Scientists. You can also build Porcelain Tower for another Scientist. These you'll bulb to help get through the mid game techs towards Radio. You want your capital to working the guilds, building Wonders etc - the rest of your cities are just supporting your capital in fulfilling that role.
Religion
For Pantheon Desert Folklore is a no-brainer. The faith is mainly so you can buy a lot of Great Engineers in the Industrial Period to rush Wonders and Artists/Writers.
The only other belief I'd say is essential is Religious Communities - you really want that +15% production. Your first settler will head to Sinai get more faith from that mountain.
Policies
For policies I still maintain that Honor, then Tradition or Tradition opener then Honor opener then Tradition is the way to go. You'll leave barb camps alone simply to farm barbs for culture unless you get Citystate rewards from camps or they are in the way of a new citysite. The Honor opener makes your military a bit stronger so you don't require as many units - this leaves you more time to build other things. Aside from your initial scouting don't try and take on all the barbs on your own landmass just keep your units around your capital farming culture from barbs until you have a war chariot and a settler ready to expand.
From Tradition put a point in Aesthetics until you get to Rationalism. For Rationalism I'd just put a point in the opener and Secularism and then go back to Aesthetics. The rest of the Rationalism policies aren't that important right now and you can use Research Agreements to give an intermediate tech boost. You may need to put a policy in Exploration to unlock the Louvre.
Freedom is your best Ideology for this strategy and I would time Oxford University to unlock Radio. Obviously you want the Tower of Liberty and the T3 policy that generates tourism from Broadcast Towers.
