Wow, is it me or are there STILL a metric frag-ton of SW D6 fans out there? The game has been out of print for at least what, ten years now?
West End Star Wars for life.
West End Star Wars = teh awesome
d20 Star Wars = teh cancer
I like the D6 over the D20 as well, having played both (the D20 one only very shortly).
One of the settings I like most is the L5R setting, as it is quite detailed with rich history. As the results of the card game tournaments are used in the official history (including the roleplay) you sometimes get strange twists, but the design team does it's very best to put it all in (up to the point of having typos on the cards explained in detail so it makes sense).
Another system I really like, but setting and system, is Alternity Dark Matter. It's been out of print for quite some time, but it just keeps going. And as DArk Matter is based on conspiracy theories, aliens and more of that stuff, as GM you can do pretty much whatever you want with it.
