I know there are a handful of zodiac traits out there, but they're all CAS traits and I've always kind of felt that it'd work better as a 'reward' trait of sorts, like how the MBTI traits in Slice of Life work. I also thought it'd be cool if, with seasons, they could be correlated to the time of year sims are born?
I was toying with the idea of translating sims 1/2 personality points & zodiacs into 4 here (https://docs.google.com/document/d/1EYmqJdspDb6kyXyW_g_t_PLtgIGG4Faphud5wjPztQ0/edit), but I know next to nothing about modding & pretty quickly realized I'm in wayyy over my head... You could maybe correlate the signs to their Jungian archetypes as well (https://www.completehoroscope.org/astrology/zodiac-archetypes.htm) if you need pointers for what characteristics each trait would have??
I was also thinking that you could add a "Take Personality Test..." interaction on computers as a way of weaving the SOL personality types into gameplay in a more seamless manner? After which, you're given a choice between manually choosing, and getting one based on your sims traits, just like the mod currently is.
You could maybe do something similar with the Zodiac traits as well, by having a "check horoscope" or "calculate birth chart" interaction on computers, where, again, you either choose manually or are automatically given one based on what season your sim was born in. And if someone uses the "Ask Sign" on a sim who hasn't had a zodiac trait assigned, they could say they don't know or aren't interested in astrology or something.
Just some ideas I had!! Who knows, with all this quarantine--induced extra free time, maybe I'll end up learning how to mod & make it myself :p
