Blue Moon City - the board game - picks up where the two-player game, (Blue Moon), ended: the reconstruction of the destroyed city of Blue Moon. The board, illustrated by Franz Vohwinkel as well as many well-known American fantasy artists, consists of 21 large building tiles, which show building plans on one side and the buildings in their reconstructed glory on the other. As in the 2-player game, the game includes 3 large molded plastic dragons.
At the start of the game, the board tiles all show their building plan sides. The object of the game is to use cards featuring the races of Blue Moon to help rebuild the city and, at the end, put the large Crystal of the Obelisk in the middle of the city back together. Whenever a building is completely rebuilt, its tile is turned back over to its rebuilt side. The players who helped with a building get crystals and dragon favors, which can be traded in for crystals at certain times.
