I didn’t get the impression that it makes it easier to get two sims together if they’re opposites. It’s just a type of connection they have based on their relationship.

Yeah, this seems more like a thing you’d earn once they’ve already started dating or something, not a thing the game just dumps on you because a cheerful and gloomy sims locked eyes once.

This thread makes me wonder about how the game will handle sentiments for premade/cas sims.
