@Pizza_is_good ok first off, something must be wrong with me because I neglected to mention how much I love your screen name.
Secondly, as I said, all her likes and dislikes are pretty much my own, but heightened for comedic effect/drama???, so it’s less that I came up with all this stuff on my own, and more that…it’s pretty much me but if I got to hang out with four hot vampires and also I had a job.
I know you said you find it uncomfortable to play as yourself, but…that’s kinda the only way I play?
My first playthrough is as myself so I can get acquainted with the world without wondering what choices would make for an interesting character.
By my third playthrough I’ve mostly solidified an exaggerated personality of myself, and then I start delving into the backstory and trying to figure out what makes them tick.
So, for example
Charlotte had a very strained relationship with Rebecca because she felt neglected, and deep down is a very lonely person. From there, I snowballed her love of Star Wars to being a bit of an emotional and social crutch for her the way comic books were to me (and also Star Wars). When I felt lonely I could read superhero comic books and feel like I really knew them,
like they were my friends??? oh man I wanna hug poor eleven year old me, and I figure Charlotte felt the same way with Star Wars.
From there, I figured she’d be more interested in science and tech because her entire goal in high school was to build a lightsaber, and that’s why she has a high science stat.
But because she has to end up a detective, I have to explain to myself how she went from being a biology major “Ok, but what if medichlorians were real?” to cop.
Thank god Sera supplied the choice of us only being able to find science work in the police department.
As a result, I figured that since her job depended on interacting with the public, Charlotte grew out of her shell and became more sociable (especially with a partner like Tina, whom she could emulate and look up to).
All this from wondering what a Star Wars loving geek’s childhood would have looked like with an absentee-ish mother.
I hope that helps give you an idea how my thought process works in differentiating myself from Charlotte, so maybe you can possibly apply it to your own characters.
