id like more realism in some areas like
more passionate romance interactions (not more explicit than the ones we already have just more passionate versions of them)
giving birth not being super weird??? like you dont have to see the undercarriage but like a "normal" birthing pose and the person you bring along holding your birthing sims hand and the doctor at the end of the bed. (also homebirth on the bed in a simillar way maybe?)
being angry with someone having more lasting impact, same with loosing a friendship. (buffs last longer)
drinking too much juice gives you the goofy walkstyle for the duration of the "too much juice" buff and that the addicted to juice or whatever its called quirk from get famous is a temp trait you can get (like the infected trait from strangerville). if you drink too much juice too many days in a row and then gets a "tense" moodlet when your sim with that quirk/temp trait stop drinking all toghether and you sort of have to weather it out to get "clean" again. would make great storytelling potential etc.
an attraction system!
just stuff like that.
