From the Publisher:
China: The Chinese economy is structured as a planned economy. In this version of the game, there are no surprises. The power plants on the power plant market are offered in ascending order during the two first steps of the game. Additionally the resource table is designed such that resources are likely to be in short supply as the game proceeds. Thus, players must plan their resource needs very carefully or find their grid dark and their incomes reduced.
Korea: Due to the division of the country, the political situation is very different from the countries of the other Power Grid maps. The players are confronted first with richly varying geographical challenges, making building expensive. In addition, because of the political division, the players must buy their resources from a divided market.
Note: In order to play this game you need to have Power Grid
