Sun and Moon The Astral Game
Sun and Moon is an abstract strategy game for two players symbolizing the struggle between the royal pony sisters that ended with the younger princess being imprisoned in the moon.

Major contributors to development and testing include (in alphabetical order) Blaze-Drag [http://blaze-drag.deviantart.com/], Caerdwyn [http://caerdwyn.deviantart.com/], chowdahrogansorah [http://chowdahrogansorah.deviantart.com/], NightMareMoonBN [http://nightmaremoonbn.deviantart.com/], Ganondox [http://ganondox.deviantart.com/], timgil [http://timgil.deviantart.com/], and TopGull [http://topgull.deviantart.com/]. Ganondox [http://ganondox.deviantart.com/] was inspired to create an new, but conceptually similar, strategy game called Randleshackle [http://ganondox.deviantart.com/art/RANDLESHACKLE-board-game-OLD-384644217]; he needs feedback and playtesting for it.

Digital re-creations of the astral game abound. In no particular order:

Anyone else who’s finished and posted a digital version, let me know and I’ll add it.

I encourage others to create and post their own designs for the game board and playing pieces. My back-story for the game is that it arose among the unicorns in the capital city a century or two after the event, when living memory—aside from one notable exception, who wasn’t talking—was gone and the affair already was fading from history into legend. Moreover, the “modern” setting of the television series is supposed to be roughly equivalent to the 1860s–1880s in real history. There is all the room in the world for original, distinctive, and period-style designs, from classical through medieval to industrial-age.
