"Thousand Suns is a roleplaying game that takes its
inspiration from the classic literary "imperial" science fiction of the
'50s, '60s, and '70s written by authors like Poul Anderson, Isaac
Asimov, Alfred Bester, Gordon Dickson, Larry Niven, H. Beam Piper, Jerry
Pournelle, and A.E. van Vogt, among others. ... This is a complete game, providing all the rules you need to play
under one cover, from character generation to starship combat to the
creation of alien lifeforms. Also included is the Thousand Suns
"meta-setting," a flexible outline of a setting, in which certain
details have been provided, along with lots of lots of "blank spaces,"
and whose final shape and content is entirely up to each Game Master to
build upon as he wishes for his campaign."
I have mega-plus-good-oodles of to-inifity-and-beyond respect for the gaming insights and writing powers of Mr James Maliszewski of Grognardia fame.
If you like your sci-fi with a vast galaxy classic twist then perhaps this has to be a must-own - to read, play or borrow-source for your own game system.
