[Possum]

Cool stuff! Once, long long ago, in an America far far away, there was a boardgame by a company called SPI, and the name of this game was Starforce Alpha Centauri. One of the many beauties of this game was the way it laid out our arm of the galaxy in beautifully realistic detail, with all their proper names. And although the paper map was necessarily 2D (no ****, Possum), there were +/- coordinates assigned, to show relative positions "above" and "below" the "plane", thus giving you a good idea of the actual 3D positions of the star systems.
