I mean I personally would prefer they were based off the Greek Zodiac, but that's because I'm super into Astrology and my own zodiac sign describes me very accurately.
But as long as the Sims-verse ones are still loosely based off the Greek Zodiac in terms of personality, I'd be okay with it. Like maybe the Llama is based off Cancer and Sims who are Llamas tend to be more emotional than Sims from other signs, are nurturing and also see a boost to their familial relationships. Or if Cowplants are based off of, say, Aries, those Sims could be a little bit more impulsive and stubborn with a shorter temper. They wouldn't need to mention what the real life counterparts are, just as long as the inspiration is obvious to those who are into astrology.
