Couple of things about this game.
We are playing these settings in the Civ V Minor Gauntlet this month. (Do you all know about the two monthly Gauntlet competitions in the Hall-of-Fame?) The Great Plain map-script is known to have an issue with City-States. A Duel-sized map should have 4, but I think there are only 3 in this game. For the Gauntlet, you are given just the settings, not a game-save, and you can play as many (unique) maps as you like. In doing so, I think I had one map that had only 1 City-State, a few with only 2, and only 1 that actually had all 4.
The other thing - there are several routes to a culture victory. You can use the game's intended method of building museums full of works-of-art, you can use the Sacred Sites strategy, somebody developed a Greek Liberation strategy (i have never tried that one), and on Chieftain and under the right circumstances, you MIGHT be able go Liberty, choose a Great Musician for the completer, and culture-bomb your opponent. The map is a duel, so should play fast for you, so I would suggest you play several practice games to get a feel for the strategy you want to choose. My best time so far with these settings was 201 turns, and I had a Great Musician with 270 Tourism two moves from the opponent's border that I didn't get to use.
