RYU

In a galaxy far far away, there is a planetary system composed of a great big sun and nine minor planets, four of which have been developed as mercantile planets more or less under the control of politicians and guilds. On each of these planets are a merchant guild, a guild of smugglers, a bazaar and the galactic government, and players can take special actions on each of these planets.

In RYŪ, players each represent one of the other five planets in this star system, with each planet having a different type of humanoid and its own unique influences. These planets are open to prospecting, and with the proper financing players will be able to dig the resources they need to build their own RYŪ, a mother ship composed of "Rare Metal", "Memory Stone", and "Amber Magic". Once assembled, the RYŪ comes to life as a living spaceship, and its owner wins the game.
