I plan to pick up the main Traveller book PDF for GURPs this weekend. Other books I happen to own for GURPS include Psionics, Magic, Mecha, and Dragons (it's hardback). From those who've tried the system what other books would be good to pick up?Assuming that you mean the 3rd-Edition version of GURPS Traveller, I believe that GURPS Space is an official prerequisite. (I heard that this is not true of the "Interstellar Wars" book, but that's for 4th Edition.)
GURPS Space is not a bad idea, but you can survive without it. Someone already mentioned First In. Of the non-Traveller GURPS Books, I'd suggest GURPS Hi-Tech and Ultra-Tech (for all of the hardware goodies), though be sure to read about the technical limitations in the Traveller setting.
Note that you *could* run a Traveller game with nothing but the Basic Set and GURPS Traveller.
