When I was younger and had time to run three different RPG campaigns at once, I had two main flavors of game inspiration: swords and guns.
For swords I usually drifted to D&D but for guns, I turned to Star Wars (at least until we got hold of Alternity). All of the excitement of blasters and spaceships without having to understand mass rations and deltaV and Hohmann transfer orbits.
Star Wars neatly fills a niche known as "Science-Fantasy" - all the fantastic story-telling benefits of science fiction with the implicit belief suspension of fantasy. Perhaps its my scientific bent, but almost every other scifi campaign I ran in any other system disintegrated after exposure to micro gravity, time dilation, and interstellar radiation.
For whatever reason, our games were always 95% Han Solo and Jabba the Hutt and 5% Empire and Rebellion, but knowing all that was going on in the foreground made the skulking back-alley deals and betrayals more interesting; all smuggling and bounty hunters, less epic battle between Light and Dark.
The d6 system itself holds up better than old versions of D&D, but still gets bogged down (if memory serves) under glacial character creation due largely to the need to look up every skill in the game while making a character then spending an hour flipping through tables buying equipment. Also, adding up huge piles of dice for every roll, then looking at charts...
In spite of the limitations of said mechanics, it's still probably my favorite Star Wars system.
All said, a solid staple of my roleplaying days of yore, including a game that ran from 8th grade until 10th with the same characters.
I'm having a hard time tracking down the ISBN's for a lot of the games I used to play, as the original pulblishers have lost the rights to the product (Cthulhu, Star Wars, et cetera) and new places are publishing new games that have nothing to do with the one's I played. West End Games is out of business? Dear god, I just found out FASA is gone! Sigh. I'm okay. Anyway, this book had a few good idea, but my pain issue was that I couldn't get into gaming in the Star Wars universe. The movies (just the three at the time) were so about the rebellion than I couldn't come up with campaigns or one-off plots, so our sessions always floundered. I think its just that, other than Shadow Run, I could never get into a non Fantasy RPG. Just me, so the game might be fine.
