Simscest is wincest... for now.

 The Sims, the game where you can be a god and control the lives of a Sim little family. Work, own a house, deal with all the stuff related to being a homeowner, get married, have kids, get disappointed with life, so you make a pool to have a pool party for your family and then let the video explain.

There are plenty of ways to kill your sims...

But it's not death what I want to speak about... it's about love... a Special Kind of love...

Yes, we have Incest in The Sims 4. It's not intentionally made. Need to point this out befre we get parent's groups going REEEEEEE!! This is a bug on the wants/desires feature. IIRC, the feature worked with Sims that had a high level of compatibility and got along with each other. Normally this excludes family members. Seems that the recent update messed that up and now we have The Sims: Sweet Home Alabama edition. EA is working on a patch to fix this issue. 

Personally, I don't have an issue with Simscest. Here come the torches and pitchforks... wait, hear me out. I'm talking about the consensual relationship between two virtual adults. Not Real Humans and no children (virtual or otherwise). The sims has ghosts, vampires, werewolves and other unrealistic things. The biggest reasons for people being against incest are mostly based on religious taboos and the possibility of malformed genetic aberrations... but that's on the real world, not The Sims. If your Sim Sister falls in love with you, you DON'T HAVE TO RECIPROCATE her feelings. This would require a Consent pop-up, which would be nice since some Sims are super easy and others, well, any more obtuse they'd be avenging Iwao Hazuki. 

But this is a videogame, it's not real and since it's not real, I'm a bit more tolerant of incest than I'd be in the real world. There are far more complex issues in the real world that make actual incest less acceptable than on The Sims... things like power dynamics that can be abusive, age differences between the two people involved (where one could've been a minor groomed by the adult), should the couple be sterilized due to risk of genetic malformations (assuming they're a heterosexual couple or non-heterosexual couple with fully functional heterosexual genitalia)... I am ignoring the religious taboo aspect of it and focusing on the social and biological aspects, because the religious argument boils down to it's bad because religion says it's bad. Would I be OK with real life incest between two consenting adults in a relationship that both parties have equal power and have taken precautions to avoid reproduction (ie: vasectomy, removal of ovaries)? I don't think so. It's kinda like GTA... I'm OK with stealing cars, killing people indiscriminately, causing all sorts of mayhem IN THE GAME, but not in real life. But it seems that many have a hang up with incest that even fake incest between fake human analogs bothers them. This rant took a weird turn...

So, if you're into virtual incest with the Sims, hurry up before they patch the accidental incest...

Update

It got patched... Sims are no longer from Alabama.
