Most modifications, or "mods," for “The Sims” are character creation, object or landscape related, but every so often a modder will create something to manipulate their Sims’ behaviors.

Modder BIlly Rand has taken some liberties with his coding skills to create a mod that allows “Sims 4” users to add teen pregnancy incest and polygamy (click here to check out the mod).

A mod is a modification made to a game using programming code. The mod codes can be used to replace skin textures, add objects, remove sensors, etc.

Some fans are upset the mods like the one for “incest” exists, but it’s not the first time modders have added more “adult themes” content in the “Sims 4.” There is a “Naked Woohoo” mod that allows “Sims 4” characters to hop into bed naked before "playing" under the sheets.

Another mod allows for same-sex pregnancy where two characters of the same gender can try for a baby (yes, men can get pregnant with this mod).

There is also a nudity mod that removes the pixelated sensors when characters use the bathroom, shower, breastfeed and streak. That said, even if gamers install the nudity mods, their Sims characters would look like dolls with no male or female anatomy showing (unless the player has installed a more realisitc skin mod).

Not all mods are as raunchy as the nudity mods. Some mods allow gamers to recreate the sets of their favorite shows, create their favorite superheroes, import clothing from their favorite brands, etc.
