Age of Steam Exp - Moon/Berlin Wall
The Age of Steam: Moon Expansion is an extremely challenging map set on the Moon where half the cities are always black and the track can be built off one side of the board, only to appear on the opposite side.
The Berlin Wall Expansion, meanwhile, takes Age of Steam back to the era of the Cold War and the divided city of Berlin. Troop garrisons impede goods movement for much of the game, and the wall also presents an imposing obstacle. Of course, the fall of the wall in 1989 changes everything.
