It will be a little while before I can start, I have another sims project of my own going right now. I'm collecting all the info I can, so I will be ready for when I start.
I have another question;
After creating my first sim, I play for a day or two. I decide to adopt a child, not to be an heir. I just want to adopt the kid to handle the fishing side and paint all portraits of the founder. Then have my founder get hitched to a townie and have the heir. Could I do that, or would I have to wait until after the heir is born to adopt the child? The rules didn't go into detail on this, they just say that adopted sims can't be heirs.
