I've just started a save where I'm pairing up various premades to see how their offspring turn out. I'm concentrating on sims who start out single, and also not looking to make a comprehensive list of everyone x everyone else, just some select couples. Many of the results will go to my library for later use. It's my way of making originals who don't all look the same. I'm not going to name anyone, just in case they also frequent this forum, but there's a few creators who share some really well done sims... except, put them side by side, and every one of them has the exact same face.
So far, I've paired these couples up:
Marcus Flex and Nalani Maha'ai. (I may be spelling her name wrong. The homeless premade mermaid.)
Adrian Scott and Summer Holiday.
Don Lothario and Eva Capricciosa.
Wolfgang Munch and Candy Behr. Wolfgang has been aged up and given a better personality. This is about what the kids look like, not drama!
I think I'll match up Vlad with Gemma charm, out of morbid curiosity. And Johnny Zest with either Babs L'Amour, or, if I can figure out what her name is, a girl who was in the City Living trailer. I know she's been shared by Maxis, but I don't know her name! Babs L'Amour, if you aren't familiar with her, is from the base game trailer, and appeared in other releases I think.
And if anyone has more suggestions for who I should pair up, I'd love to hear them!
*Found her! Her name is Jordan Mayer. Also, wow, there's a lot of cast members from various trailers. And the template sims who are in CAS when you start a new game? They have names, and can be downloaded as originally created! I had no idea.
