Power Grid: Bremen/Manhattan is a pair of expansion maps for Power Grid!

• The fight of the electric power companies in Bremen for the most customers is particularly tough and fast. Nuclear power plants are not used to supply electricity in Bremen so you are fighting more for scarce resources. Unlike the other game boards Bremen does not have classic connecting costs between cities, but instead flat district costs. Additionally, several districts are so small, that they are limited to two spaces for networks and afterward do not allow further competition.
• Manhattan has a giant demand for electric power, but does not have much space for the necessary networks. Thus, the electric power companies fight nonstop for the cheapest building costs all over Manhattan. This map only offers a single huge area and the game only runs in Step 1 until the end of the game.
