BX-Space

From the introduction:

The purpose of BX-Space is to set forth the basic tenets of Dungeons in Outer Space Science-Fantasy. The intent is to create additional rules which “bolt-on” to classic rules or known rules which emulate the RPG rules of the 1980s.

Stylistically the theme of BX Space is necessarily one of a Medieval Futurism. Far from realistic, in our science fantasy almost any planet in orbit of a sun may be expected to be inhabited by strange alien monsters and on most planets the characters may come and go without using a Space Suit. For the most part Space Suits are only used – in the vacuum of space!
