I figured I repost this as I recall it being fairly popular.
There was a thread on the Name Opinions Message Board a little while ago where two players went back and forth with their favorite names to eventually compromise on a name they would name a child in real life. It was quite popular, and I've been thinking about introducing it to this board. I've changed it up a bit in order to create actual families.
A relationship is all about compromise, so post your ideal family—amount of children plus favorite names you would use in real life—and prepare to compromise with another player.
In terms of number of children, either find a middle ground that pleases opposing preferences or maybe you're lucky and both "parents" want the same amount. Or the amount of children could be so unsolvable that your fictional relationship ends in a messy divorce! For gender, either choose or flip a coin (https://www.random.org/coins/?num=1&cur=60-usd.0010c)—heads for a boy, tails for a girl.
In real life, the parents would have to call their children by their given names for their whole lives, so both "parents" in this game must at least like the names. Be ruthless in vetoing your partners names, just as you would in real life. You post names, your partner keeps some, vetoes some, and proposes new names. You do the same thing, and it goes back and forth until you feel there are enough names to create your family. Create combos, and name those fictional children!
Have fun!
