Solarquest: SolarQuest is a space-age real estate trading board game published in 1985 and developed by Valen Brost, after his having conceived the idea in 1976.  The game is patterned after "Monopoly" but replaces pewter tokens with rocketships and hotels with metallic fuel stations.  Players travel around the sun acquiring planet, moon, and man-made space structure monopolies while fending off attacks.  They seek to knock their opponents out of the game through bankruptcy, as well as optional laser blasts and dwindling fuel supplies (when using the Advanced Play ruleset).

CirKis: CirKis is a piece placing board game, for two to four players, invented by Phil E. Orbanes and developed by Winning Moves Games USA in 2009.  However, the game is no longer in production.  It received the French Game of the Year Award for 2009.  The game is based on Penrose tiling.
