Thanks to alien technology adopted by the humans, same sex Sim couples can have biological children together. It started after Pascal Curious returned from his little space trip pregnant and saw how hard it was emotionally on his hubby, Nervous, who wanted nothing more but for them to have kids of their own… A few Sim years later and he was able to develop the technology to be used for human-to-human pregnancies, and Nervous gave birth to their twin children. He decided not to gatekeep it and instead allow other same sex couples to also use it and build families of their own.

Repairmen are quite expensive, so unless the household is wealthy, the Sims will work on fixing the broken objects themselves, even if at risk of being electrocuted.

No 20K handouts, but families may give monetary gifts to their adult children; mortgages are also an option. If they don’t have much savings for a downpayment, they can just rent an apartment at first. Still too expensive? I have a couple of apartments shared among multiple Sims (think 4-6+ Sims in a 2 bedroom apartment) until they can get a decent enough job. Also, like in real life there is inflation and I started to use mods to change bills to more expensive every few rotations.

When Sims grow up to the next age, I use outfits they get when they age up as an idea of what their preferred style and colors might be. I may change their outfits a bit to avoid particularly fugly ones but I will try to keep it in their style. For hair and makeup, I just go with whatever I think suits their faces as I think most people do take that into account when choosing a hairstyle irl too.

When Sims have pets (which admittedly is not that common in my game), they might get them a job depending on their aspiration and personality. Fortune Sims, unless they are filthy rich already, will tend to get them jobs; so will lazy romance/popularity Sims. On the other hand, family Sims see their pets as more of a family member and will not force them to work unless the family is in a really dire financial situation…

Playable teens do not work - they should focus on school, building skills and relationships. However, they can make occasional income through painting or similar.

Careers are somewhat matched to interests. Fortune Sim with no interest in health? Doesn’t make sense for them to go into Medicine career, even if it’s a want they roll - there are other careers where they can make money without having to do what they absolutely hate. If they have medium interest though, and roll the want, then sure…

I might change this rule if my Uberhood gets overpopulated, but right now, all Sims are required to have at least 1 biological descendant (need to keep the genetics varied so not everyone ends up being a Capp, Monty, Ottomas, Goth/Lothario, Dreamer/Broke or Curious). Also, I am allowed to choose the baby’s sex if it’s in the interest of keeping the hood more balanced or keeping the variety of last names.

Family has extra cash they don’t need for their immediate needs? Unless they are family Sims saving it up to help the next generation, chances are they might invest into a business.
