Yeah, North Korea's gone which is a shame. After seeing Shiri, and the training sequence is cool, I wanted to do something like it. Briefly, here's some of the information on Korea in 2060. You can find page references and more information in the Asia Index that I posted in the
other thread.Korea's run by some guy with the title of President-General so I figure that it's like the several times in the past where the military have taken over running the country.
Target: Smuggler Havens has some information on Korea and mentions that the Japanese regularly sending naval warships to visit Korean ports to remind them who's calling the shots. Of course, after Year of the Comet that's all changed. Also mentions the major ports of Pusan, Wonsan and Ch'ongjin and that Korean pirates make a point of hitting Japanese shipping.
Seoul has an active Shadowland node. Blood in the Boardroom has some information on Eastern Tiger Corporation and Kwonsham Industries, two Korean corporations that belong to the Pacific Prosperity Group. And the novel Tails You Lose, I
think although I can't be sure, mentions a Korean company that's run by a dragon.
Even if North Korea is gone, I'm sure you wouldn't have much if any trouble dropping something similar into the Shadowrun world- Yakut (Awakened Siberia) would be a good choice IMO. Breakaway province, continuous low-level border warfare and fairly insular with little known about their internal structure or government yet wanting to exapnd and take Russian territory.
