Last summer I had the pleasure of visiting North Korea (with Koryo Tours). I think it's worth noting that the company is not North Korean -- it's based in Beijing and run by British expats.
No no no, Koryo Tours is a tour company run by Brits. They're just a tour company. They don't do programming. The programmers are with NovoTek in North Korea. Koryo Tours paid NovoTek to make the game.
