Power Grid: Australia/Indian Subcontinent is a couple of expansions for Power Grid!
Australia does not have a single unified power network. Only in the populated regions, mainly in the south east region, are several cities connected to each other. Because of this, players may connect to any city for a connection cost that's typically higher than normal. Australia does not use uranium for its power generation, but it does mine huge amounts of the material to sell to other countries. This offers a completely new game element, even for seasoned Power Grid players!
The Indian Subcontinent is always in danger of suffering huge power outages if the players grow their networks too quickly. In addition, the players must buy their resources on a limited resource market, which does not always guarantee enough resources for all players.
