Dear Moderator Elves
If you have a child born that you might have pursue the Rancherino Big Dream, at what point do you set the Off Grid and Simple Living traits? As soon as they're born or when they become a teen (& start running errands).
If the answer is "from birth", does that mean that you can only choose this Big Dream for a born-in-household Sim if you choose it straight away and set the lot traits? Otherwise, I can see some wiggle room if you don't choose the Big Dreams until your child ages up...
Warm wishes for the season
I agree with GlazeyLady's interpretation of when to select the Simple Living and Off-the-Grid lots with a slight addition:
*Move-in spouses and adopted children: After the Watcher has both (1) moved them in and (2) decided on Rancherino as their Big Dream.
*Born-in-household sims: As soon as the Watcher decides on Racherino as a sim's Big Dream.
Don't fear the Off-the-Grid lot challenge. You can surround your Rancherino with siblings who also have low-tech Big Dreams.
Note: a sim child can technically begin working on Rancherino requirements by buying/planting crops, collecting colored eggs needed for Animal Treats, befriend wild animals, and so on.
For example, I'd already chose Rancherino for one of my founders so I set Simple Living & Off-the-Grid as soon as I went into Live Mode the first time in my dynasty challenge.
GlazeyLady planned for Mason to become a Rancherino before his birth, so she set the two lot challenges after he was born.
