[GURPS] What books do I need?

[Thalnawr]

So, I'm getting close to the end of my current D&D campaign, and I kinda want to try out GURPS for a space-pirates type game. What books would I need to purchase in order to cover the basics?

Besides the two basic set books, Space for genre discussion about adventures in space, the Spaceships series for spaceship combat and trading and Ultra-tech for futuristic items. Perhaps High-tech for more modern stuff, Psionic Powers if you're allowing that and Bio-tech for more technology.

[Yuki Akuma]

You can do everything with the two Basic Set books. Other books give more items, advantages and optional rules, but you don't need them.

I'll have to check what's available for sale at our local game shop, I suppose.

I haven't played in years, so I don't know how much the newest version might have changed, but if you're playing fantasy GURPS I can say that once upon a time you'd absolutely have wanted to get GURPS Fantasy and GURPS Religion (the second one is a great buy for any fantasy game).

I've browsed the vast majority of them, but like Yuki_Akuma said, you only need the two core books. Other than that, I'd definitely suggest Powers, since it nearly doubles your options (well, a decent part of it is obvious suggestions...) but only if you've got some extra money lying around. I don't actually have it, myself. I don't remember any of the space-themed books being particularly useful other than providing examples, but I could be wrong.
