Note: This is written from the perspective of the end of Week Six, so if you don't want spoilers, don't read it.
I tend to think about potential future spouses for my Prosperity Sims while they're still in elementary school. This is partly because I'm just controlling like that and partly because I want to intermarry them as much as possible rather than having a constant influx of townies.
There are a couple of factors which complicate intermarriage. One is a gender imbalance. I currently have five single women living in two different houses because there simply were not enough men for them without bringing in a ton of townies. I kind of wonder if the girl skew is built into the game somehow; I know a lot of people who have it.
I actually don't have a girl skew among my current batch of teens and children, though. Prosperity Plains currently has 24 residents between the ages of 5 and 22 years; of those 14 are male and 10 are female.
"Great," you think, "That just leaves 4 guys who have to find townies or marry some of those older women or something."
Not quite. We now come to the second problem with intermarriage: Once you've done it for a generation, everyone is related. Of those 24 young people, no less than fifteen are Beata Riedmayer-Landgraab's grandchildren. Namely: Landon and Ginny Whitfill; Joe, Seth, Jeannie, Gabe, Edward, and Brian Pons; Todd, Fritz, and Charles Riedmayer; and Lauren, River, Elijah, and Tamara Whitfill. (That's 10 boys and 5 girls.)
All the Whitfills listed above are cousins on their fathers' side to Emmy and Shelley Whitfill.
Emmy and Shelley are cousins on their mothers' side to Caitlin and Patrick Seifert.
The only kids who don't have cousins are Alexis, Silas, and Priscilla Kules (Alexis is aunt to the other two), and Charles and William King. (Charles and William are half-brothers to the three Riedmayer boys, though.)
I'm sure you're not following at all at this point, but that's okay.
So, let's look at it from the perspective of the Riedmayer-Landgraab cousins. There are 10 boys, most of whom want wives. They cannot marry their first cousins, so that leaves them Emmy, Shelley, Caitlin, Alexis, and Priscilla. Already that gives us 5 single guys instead of the 4 we would have if nobody had been first cousins.
Meanwhile, there are 5 girl cousins. They have a little more choice, with Patrick Seifert, Silas Kules, and Charles and William King. (Though that does mean that two of them will have to marry their cousins' half-brothers. My brain hurts.) Still, that leaves one girl who won't have a husband unless she goes for townies or marries a much younger man.
It'd completely take care of the problem if Ginny or Tamara rolled Romance (or Pleasure with a 50 first dates LTW), but if not somebody who's Knowledge or Fortune can be an old maid. (If any of the non-cousin girls roll Romance, they're getting rerolled in college.)
As for the guys: Joe Pons and Charles Riedmayer are Romance (20 lovers LTW, too) and Todd Riedmayer is a 50-first-dates Pleasure. So those three will probably establish a happy bachelor pad. None of Joe's brothers can join them, though, because six of the seven Pons children have to marry to fulfill Joan's lifetime want. (So far, Joe has the most family-unfriendly aspiration.) Landon Whitfill can't join them either, because he's the heir to an original house and has to marry and keep it in the family--which means that if he rolls Romance he'll follow in his father's footsteps and reroll in college. Fritz Riedmayer is Family aspiration and I'd like one of the those brothers to pass on their genes so I'd rather not reroll him. Elijah is the only prospect, therefore; I guess we'll see what he rolls when he becomes a teen.
(There is currently a female placeholder in college who will marry the last spare boy, probably one of the Ponses, so there only need to be 4, not 5, in our hypothetical bachelor pad.)
This is why I don't do love-matches. Even if there are a handful of girls who aren't your cousin, some of them are probably your cousin's cousins and you have to marry the one who isn't so your cousin still has someone to marry... Better just to say to my Sims from the beginning, "Okay, Brian, I realize you have three bolts with Priscilla, but if you marry her Landon won't have anyone to marry. So you can marry Shelley; I'll even have her dye her hair to the color you prefer." (All of the Sims in that example sentence are still children, so I don't know how their attraction scores will end up.)
That was random, but I had fun writing it. I promise the next post will be Week Six Part One.
