@Errol: Why is China in your Vietnam stupid? More than a couple of dynasties made forays into Annam and/or made tributaries out of the various Vietnamese client states.
I don't like the regularity with which it happens. It's not quite as bad as Korea all over the place (Vietnam, Xia), but the borders in this game are still hella ugly. Chinese enclaves everywhere, no land connections... like half of their lands are terribly administrated. And they keep growing.
Also, it's an aspect of the big bad Mingblob. Stupid damn Mingblob does not appreciate your efforts to become the dominant power of the far east.
And even if you through sheer tenacity, attrition and disregard of the forcelimit manage to get them out of Korea and occupy Nanjing while at it, even if you beat Qing into giving you the rest of Korea they held on to - at once, this time - even of you force release Fang holding most of the east coast provinces (including Nanjing), cutting their income by a third and finally denying them the strait to Taiwan - they just don't stop. It's getting ridiculous.
Actually, this time it wasn't Ming who started the war. It's been Qing. But they are allied to Ming with superglue. And Qing also has an alliance with Fang, which, for some reason, takes priority over mine, in a war they started. Sigh.
This time, I am not going to stop until China looks like the goddamn Balkans on steroids. Fuckers should consider themselves warned.
