Age of Steam: Denmark was designed for commercial publication but is now made available as a free print-and-play expansion for the Age of Steam base game. This map is intended to be played with 3 to 6 players, with the map reputedly playing best with 3. Denmark has a both a new economic system (an extension on the one seen in Age of Steam Expansion: South East Australia), plus an entirely different Locomotive action and system of managing and upgrading links.
