@branman65 @flux_the_cat @Zettour If you really start delving into Star Wars, you'll quickly find that both "light" and "dark" are just two extremes and self-annihilate each other. This wasn't intentional and wasn't fleshed out much by Lucas originally.
"Light" side characters are altruistic and self-sacrificing to the point of their own destruction.
"Dark" side characters are passionate, jealous, and can't tolerate being under someone else's rule for long without trying to usurp them, also unto their own destruction.
"Grey" jedi are moral cowards afraid to pick a side at best; vaguely good guys at worst and not really "grey" just more willing to break the law to do some good.
There is no "based" side in those parameters, though there are Expanded Universe books where it is revealed that the majority of the Galactic Empire enjoys peace and prosperity, even the non-humans, as the empire routs out and destroys pirates and brigands constantly. That the "Rebel Alliance" is led by some ex-nobles looking to get their fortunes back and to restore a republic that was dying to infighting in the first place, even before Palpatine.
I always liked playing as the Empire factions in games that let you do it. I was looking forward to a sequel to "Republic Commando" where it's "Imperial Commando", but I know better now that it would probably just have them defect to the rebels eventually anyway, even if Disney had never bought Star Wars. Which would be lame.
