I'm currently in a Star Wars PnP group. For the first time in the fifteen odd years I've been doung Tabletop on and off, my current PC marks the first time I ever played a character that had a full fledged backstory, limitations and moral compass separate from my own. Usually I either roll a fascimile of myself, or a gimmick character with a clear mechanical hook.
It's been both fascinating and annoyingly obtuse having to roleplay out an honest reaction to something I myself would either not care about, or be completely opposed to. Seeing the CR guys take things so seriously is exhausting. Even after the two other players and I had out big philosophical debate on the right course of action, I, out of character, was like, "alright look, the pathos is getting tiring, how do we actually want to do this? I'll act out my PC in a way that lets it happen."
My PC's schtick is that he's a Twi-Lek Bounty-Hunter who freed himself from Hutt slavers and now does odd job hunts in the Empire. For him, The Empire is another monolithic entity he has no chance of stopping. He couldn't kill his former Hutt master, and they're as powerful as the Imperials. He cares about survival and little else. He's also not that smart, only an Int of 2 (out of 5 Max).
One of our other PCs is a boy-scout wannabe rebel who's pestering the party to take the fight to the Empire while the last one is a character born during the chaos of the Clone Wars and understands the peace the Empire brought. Our party just saw, first hand, the brutality of the Empire as they occupied a colony world. All three of us got into an in-character debate over how to proceed. For my PC, he was relatively unphased by the executions and the martial law- the Hutts are no better, he'd seen it all before. I argued, legitimately in earnest, that this was not our fight, we're bounty-hunters taking in marks, nothing more. Let some other fool, like the Blonde pretty-boy with the blue lasersword, figure it out. The PC who'd been born into the Empire was having a crisis of faith because he does generally believe the propaganda. It just kept going and going until our GM just told us he'd written more for Rebels than Empire. At that point I just pulled a Han Solo and agreed on the condition I get the biggest share of credits.
Fuck me man, the people who actually sit there and get into it to the point of emotion are nuts.
