Many moons ago I used to play role-playing games and one of my favourites was the Star Wars D6 system. The universe was so well known that it was easy to get players and the system itself was dead easy to explain. That meant I could concentrate on the story and the characters rather than the game mechanics.
Anyway, I'm now selling all my Star Wars D6 books. They date back to the late 80's (1987-1989) but are in quite good nick considering they were so well used.
The auctions are here on eBay.
