I just want it to be a real attraction system, so if your sim doesn't like sims with brown hair, they won't be able to romance them at all. No more romancing everyone. If sims aren't attracted to someone, then they shouldn't romance them at all.
slight disagree because id still like to have sims able to romance regardless of their perhaps misguided genetics bias
like maybe sim has always found blonde hair ugly but then they meet sim thats otherwise a snacc and decide that dang okay ill accept u regardless of blonde hair
it should just be a lot harder to match sims that dislike everything about each others looks tho and they shouldn't autonomously romance people they find somehow unlikeable
