I loved playing SW in the d6 system back in the day. d6 pools definitively resonated with me, enough that when I recently created my own RPG engine it ended up as d6 pool based, albeit with some interesting tricks to prevent it from becoming unwieldy and that allow for a margin of success mechanic. (It can be found here, if anyone's curious: The Aurora RPG Engine)
Totally. Rolling a d20 and adding a big number to it is fun, but there's nothing like the tactical feelings of power when you actually get to roll more dice the more powerful you are.
