Take Traveller, bloat it up a lot, make sure you have tables for as much as you can think of, including double level fatigue and dropping the ball. This comment also nails it :- “the barely sketched out campaign milieu is a mish-mash of animal-men, vulcans, jedi, lightsabres, space nazis, space commies, martians-from-War-of-the-Worlds and implacable hiveminded insectoids.” http://forum.rpg.net/showthread.php?461973-Necro-FGU-s-Space… Some very dodgy writing and concepts, but it has a certain charm, and some of the stuff you could have enhanced Traveller with..more detailed character enlistments, some effects of the planet that your character has come from, etc. How to bias stat rolling to make players likely to have higher level stats than the ordinary by using d100 to roll d20, that sort of thing. Much weapons and gear, too. The middle game I guess you could call it of Traveller and Spacemaster from the time. Worth a browse for entertainment and occasional useful part.
