Two new expansion maps for Power Grid: Russia on one side and Japan on the other.
In Russia; the market for power plants is restricted. Additionally; the standard rules for exchanging out-of-date power plants are changed; forcing the leading players to completely rethink their strategies.
In Japan; based on the crowded geographical surroundings; the players can start two separate networks. The first connections are restricted to certain cities; guaranteeing a tough fight for the best networks.
