GURPS Uplift (2nd edition), softback sourcebook, by Stefan Jones
Based on the Award-Winning Novels by David Brin.
“The Five Galaxies are a tough neighborhood . . . and humanity is the new kid on the block.
Of the thousands of races in a galaxy full of aliens, ours is the only one that claims to have evolved on its own, without genetic engineering by a Patron species. With its own new clients — genetically modified dolphins and chimpanzees — upstart humanity faces a jealous universe. The ancient Patron clans can’t decide whether to enslave the races of Terra . . . or just wipe them out.
The Galactics have wealth, power, and incredible technology. The people of Earth have guts, originality and a handful of allies . . . and they won’t give up.
This is the universe created by David Brin for his award-winning “Uplift” series. GURPS Uplift includes complete descriptions of the important alien races, maps and descriptions of the Terragens planets, and rules for creating — and Uplifting — new species.”
