I want to que up some interesting games for Victoria III, and I'm sure other people would like ideas as well.

Some fun I've had:

Venezuela, reuniting Gran Columbia without bloodshed

Columbia District, racing the US to California

Mountain Republic, playing both sides of the Egypt - Ottoman feud as an Islamic Republic trading hub in the Caucasus (Released from Russia)

Sindh, working with the Sikh Empire to undermine East India Company

Siam, starting an isolationist Monarchy but there is significant potential to be a major power in the east

Oman, with a choice between dominating trade in the Persian Gulf or focusing on Zanzibar during a succession crisis

Aside from the in-game-recommended starts of course; what interesting places have you found?
