So, Christmas time is rolling around again, and it is time to shop for gifts.

Among other things, my girlfriend has asked for the re-releases of the original Traveller books. Unfortunately, I know dick all about Traveller. Anyone mind advising me which ones (beyond the core book) one would need to run an awesome campaign?

http://www.farfuture.net/hardcopy.html is the place I am planning on ordering from, in case anyone else is looking for it.

Picture unrelated as there is no such thing as good Traveller art. I looked.
