I should have been clearer with that. Let me rephrase it.


The spouse that has currently or will bring in the next generation may unlock a restriction.
Children produced by the family may unlock restrictions.
Each generation, only one child may take on a spouse (who can unlock a restriction) and create the next generations.


For example.
You have your founder, who can unlock a restriction.
They marry a townie. If that spouse is going to be the one to help them produce the next generation, they may unlock a restriction. If they AREN'T going to help produce the next generation, then they cannot unlock a restriction.

The founder and spouse have 3 children. Each of the three children can unlock a restriction when they reach adulthood.
Only ONE of the children may bring in the next generation. The spouse of that child can unlock a restriction, but spouses of the others cannot.

So on and so fourth.

Simply:
The founder and any biological children born into the family can unlock restrictions
You may have 1 spouse per generation unlock a restriction too, but no more.

Thanks for really grilling me on this. I'll post these clarifications on the other boards.

I'm glad you guys like my challenge!

You can't finish this challenge in one generation. The only spouse that can lift a restriction is one that directly contributes to the birth of the next generation.

In fact, the ONLY Sims that can be added to the family via move-in/marriage are spouces that will produce the next generation, thus you may have only one spouse per generation.
