[LostCommander]

I never played the original, but I have most of the GURPS Traveller books by SJ Games and they are very nice. LOTS of depth and detail for whatever the group might want to do, and since it is in the GURPS system it is much easier for me to drop in random events for the PCs (they kept talking about what would happen if there was a borg cube to run into...). A Traveller shipset might be interesting.
