GURPS - Humanx

From their website:

"Man's Best Friend Is a Bug!

600 years ago, in the early 24th century, mankind met alien intelligence – the insect Thranx. Despite their physical differences, humans and thranx soon found they had much in common. Within a hundred years, they had united as the Humanx Commonwealth. Today, humans and thranx stand shoulder-to-thorax against the ruthless reptilian AAnn, defending the dozens of intelligent races and hundreds of inhabited worlds that make up the Commonwealth.

GURPS Humanx, a world book for GURPS, takes you planet-hopping through Alan Dean Foster's Humanx Commonwealth, where Ethan Fortune and Skua September sailed the Icerigger across the frozen wastes of Tran-Ky-Ky, Flinx and his minidrag Pip activated The Tar-Aiym Krang and solved the mystery of Bloodhype, and the great whales still swim the seas of Cachalot.
