I have played all versions of D6 and grok it. My goto for SW. But I have also played SW SAGA and grokked that as well. It took me a while to get used to the funny dice in FFG but when I did, I grokked that. Now that either means they are 3 excellent rpgs, or the Star Wars theme just caps system.. I have a feeling it's both.. they are all 3 very good rpgs, and the setting is evocative, well supported and deep in our geek brains.
What would I run, d6 Star Wars 2nd edition.. well you know, the WOMP RAT version..
