I cut my teeth on both comic based and star wars games. The IDEA of FCs in the latter make me skeptical for all of the reasons already articulated but I'm the same guy who feels a good Star Wars game would utilize the Empire as an NPC or alt based black hat faction. A PC faction often becomes more concerned with winning than being a story mechanism. Some folks like to play Grand Moff Mary Sue and want to win or conduct space-fantasy world simulation instead of being a plot point so my way doesn't fit all.
The thing that struck me reading this is somone like Darth Vader whose primary character trait is to dominate every scene he's in. How cool might it be to have the chance to be the one who measures the judicious terror he's supposed to bring and inject that in small doses into story?
Pretty cool, I think, and hopefully interesting for everyone involved.
But, activity requirements? That's where it gets tricky. How do you make sure a character like that is not squatting but also not burning through his story potential by having to carry on forced conversations that violate what I would think is his appeal as a story device?
I'd probably restrict him too.
Good luck to you guys though FCs are fine in an environment that is more concerned with stories than a huge amount of connections.
I'd advocate for the position that most grizzled rebellious Corellians pretty much see Luke as a naive inexperienced hillbilly who got lucky. With the setting you've selected its really just our ooc bias that wants to put them on a pedestal.
Most of their super heroics have not occurred. Especially in a setting with more spacefantasy lasersword samurai than canon.
