OK, here's a map that I like. It's playing Russia on a SMALL pangaea and has a great setup for multiple approaches at a culture victory. Other map setups that I used were hand-picked opponents (Cleo, Harald, Hojo, Roosevelt, Victoria), abundant resources, new age, no huts, no barbs, and legendary start with 11 city states. Once someone can grab the seeds you can increase the difficulty (king), but as it is, it's a great map to learn different approaches to a culture victory. Here's what I like about it:
The capital location. Tsingy is 3 tiles away and all six tiles are good- there's 3 hills for mining, 2 forests for milling, and a luxury plantation, no flat unforested tiles with no resource. Only four of the Tsingy tiles are usable in the starting location but you can move if you want. There's also lots of hills so it will be a high production capital and a great location for Ruhr, which by itself is a great setup to any victory condition.
Second, and IMO more importantly, is the other civ's starting location. 3 civs (England, Egypt and Norway) are clustered in the far west of the map. Japan is pretty far north and slightly west. America is to the east. The way they are set up, you have the option of eliminating Roosevelt early and then having the east, more than a third of the map, completely to yourself by not allowing open borders. Another option would be to go after Roosevelt and Hojo which would mean that you could control about 3/4 of the map by yourself. Just get the territorial line in the sand early, and then expand at your leisure and play Sim City.
Third, and IMO most importantly, are the city states involved and where they are located. There are eleven city states, but the five that I would focus on are all within the territory that you would claim and encapsulate them, meaning that you shouldn't have to worry about an AI conquering them. Out of the rest, the best two are also close enough that you can liberate if you need to.
The first two are my favorite combo for high culture games, Carthage plus Kumasi. The Suzy bonus from Carthage gives an extra trade route with encampments (enough of a bonus to say one extra trade route per city) and Kumasi gives some gold and tons of culture from trade routes to city states. Since each city will support 2 trade routes, you use one internally to support infrastructure development and the other to get huge bonuses from Kumasi. Third is Zanzibar, not directly tied to a CV but trade CS type-bonuses form the foundation of an economy and the extra luxuries are a big help. Fourth is Yerevan, which means that it could be a successful RV as well, but in the context of a CV means you have the option of playing religious culture, allying with Yerevan to get the martyr promotion and then suiciding them in the far east (probably Egypt) to get all the relics in the game. There's no Kandi or huts in the game so AI civs won't accidentally grab any of the relics; they're all yours if you want them. This angle works particularly well with Russia since his 1/2 price holy sites also provide one of each of the artist class great people points, so you just build those everywhere and only build theater squares as needed to house great works, and the temples can house the relics. The last of the primary five is Hong Kong which will help late game with the projects. The other two city states that have the most helpful bonuses are Brussels and Amsterdam, which you probably won't encapsulate but likely will be adjacent to so you can liberate them if necessary. Amsterdam stacks with Zanzibar for double the gold from CS type bonuses, and Brussels helps with wonders, another angle at a culture victory.
So different approaches towards a culture victory with this map are 1.) ally with Yerevan and suicide to grab ALL relics, 2.) Carthage/Kumasi combo for insane culture progress, 3.) supplement one of the previous methods with culture wonders assisted by Brussels, 4.) since you have half of the map to yourself, you can have almost the entire eastern coast and half of the northern and southern coast as seaside resorts. All of these methods are initially boosted by Tsingy in a high production capital.
The map would also be good as a religious victory because you're Russia and there's Yerevan, but I would prefer to have more religious CS in the game for RV. Also noteworthy is that Carthage in the game means you'll want lots of encampments, and there are two other militaristic CS on the map, so the encampments will have lots of unit producing boosts.
