So here is another chapter in my continuing tour through various ways to play Civilization V. Owing to real life scheduling concerns, I wanted a small game to occupy part of a week, and a one-city culture game was very much on my list to try.
Siam was a very straightforward pick for the civilization, +50% bonus yield from city-states. (Not India; an OCC doesn't have any happy problems.) City-states work very well with an OCC, since maritime food is biggest in the capital, and their culture is the same regardless of your city count.
Game parameters: Staying on Emperor difficulty, with standard size and opponent and CS count. Tiring of Pangaeas, I chose an Inland Sea map for a spin, in remembrance of my favorite Civ 4 OCC game.
