I played a game as Korea. Small, but some good resources, and also one ethnicity and religion. It’s a tributary under China, which means you pay a fee to access to their market and some military protection. I also kept good relations with Russia, Japan, and Britain.
Development was hard. I managed to get religious schools early, which improved literacy, which leads to everything else. I built out railroads in the 1860s. By 1900, Korea had the fourth largest economy, after UK, France, Austria, China. But around 1920, I had the great crash where everything went bad. I think it was a combo of not enough oil and running out of workers. I didn’t have the means to colonize and I was stuck with no migration allowed. (The only time I faced a revolt was when trying to change migration policy.)
There were some strange politics for a while. At one point, the Liberal Party consisted of Priests, Military, and Trade Unions. When that broke apart, only the Priests were in the Liberal Party. Then there was the period where each interest group had its own party. Communists peasants, Radical trade-unionists, Social-Democrat intelligentsia, Liberal Priests, plus some right-wing parties that had no power at all.
In my game, Japan got colonized by Britain around 1890. I guess they failed to industrialize. By that time, I had a small, but well-equipped, permanent army, plus the potential to mobilize a lot more. Not enough to invade anyone, but plenty to discourage any adventures into my territory.
I’m looking at Persia for my next run. Or maybe Netherlands.
The basic game loop is lots of fun: handling the politics, laws, and institutions, and all the economic juggling. I need to learn how to manage a real downturn, probably by selectively destroying some factories, etc, instead of simply growing out of it.
