Jade Dominions
East Asia in 17 realms of very different size, from the Selenga to Luzon: the Han heartland and the Khalkha steppe pay big but have many borders, while Taiwan, Ryukyu, Qiongya and Ezo are small, cheap and easy to hold. Capital Muster: a realm's bonus is mustered on its capital each turn instead of placed by hand. Every capital starts behind a neutral garrison.
