Whats up with that wish? Almost EVERY parent wants it for their kid. Offcourse I could do it, but the neighbourhood doesn't have to be populated with geniuses. Is that just my game?
Why don't they wish for other traits?

yeah, it happens to me too. I have a family with 6 kids, and their parents ALWAYS gets the wish. I don't want them all to be geniouses!

But it's logical their parents would hope for them to be.

Yes, but parents might also want to see their children be any number of positive traits, in addition to Genius. In real life, some parents hope their kids will be athletic or good or ambitious (if you read ambitious as hard-working/successful). It would be nice to see some variation in game.

they should only wish the traits that they have themselves. Is'nt it more realistic that the parents want the kid to look like themselves? None of my parents are geniuses...

I've only gotten that wish from a parent who was a genius and the parent married to a genius, so I didn't know it was universal. That's strange.

I've had several times that parents roll the wish for their child to become a doctor (lvl 5 medical). It's just one of those little nudges, you don't have to promise each wish, things don't always work out that way in RL too

I've gotten "see ___ become a genius," and "see ___ be a doctor," from various parents as well as "see ___ become evil" or "see ___ be a criminal mastermind" from loving mothers from the darkside.

Every parent in my game ha had the wish "____ becomes a Genius". One family neither parent had the trait, in fact both parents shared 2 traits (athletic, Loves outdoors) and they never wished for either of them. That doesn't make sense to me, seems like a parent would wish for their child to have one of their own traits.

I've never seen it..

I've never had it either...

Although like Aree i have had ones like 'see ___ become a doctor' but never 'see ____ become a genius'

I've found its a lot more frequent if one or both parents are geniuses. However, it isn't exclusive to that. It bugs me a bit too. I have big families, and I'm getting fairly tired of their mother or father expecting every one of their kids to be geniuses. What happened to the days where daddy would want his little boy to grow up to become athletic? What happened to the days where mummy would want her little girl to be good in the kitchen? I don't mind geniuses, but it gets a little tedious when all any sim wants to do is play chess.

In my main family, their first son was a CAS-created genius, but otherwise neither of them were geniuses. The police-officer father wanted his daughter to be a doctor, and the mother has wanted her little boy to be a criminal mastermind in two different versions of that family. She's also wanted daughters to be evil like her, but so far my geniuses haven't wanted geniuses. (Well, my only genius so far had a born-genius, but that is besides the point)

I think it's at least somewhat random, but remember, you don't have to give your sims what they want.
