In The Sims 4, the Writing skill serves as a vital avenue for creative expression for Sims and more predominantly for income generation alongside some other perks, allowing Sims to craft everything from novels to screenplays and earn royalties from their published works. With the introduction of the Life & Death expansion pack, writing takes on new significance, particularly through the new aspiration, Ghost Historian, which requires Sims to delve into the supernatural. One of the key milestones for this aspiration involves writing a Horror Book in the Sims 4.
