What is Sun and Moon?

“The Jade Sun and its counterpart, the Obsidian Moon, are the two most powerful entities in Rokugan's cosmology. Both are revered and feared in equal measure by all those who dwell within Rokugan and its Colonies.”

— The Sun Returns

  • On-demand image streaming: no need to download image packs.
  • Spectator mode for watching games in progress.

Sun and Moon was created by Drew Castalia for Benjamin Travis, who introduced me to the game when I was thirteen years old. He told me that he could rarely find others to play with; now he has the whole world. Thank you, Ben, for the inspiration!

This app is feature-complete, but open to further development. If there is sufficient demand (and I have sufficient ability), I would be interested in implementing the following:

  • More sound effects, music.
  • Voice chat.
  • Ladder rankings.
  • Win / loss and deck composition statistics.
  • Dynamic playing areas.
  • Personalization options.

Let me know if any of this appeals to you, or feel free to get started.
