The Sims Olympus was going to be an online version, similar to The Sims Online, of what is now known as The Sims 4 planned after The Sims 3's success. It however, was cancelled and instead of The Sims Olympus, The Sims 4 released. The reason for the cancelling could be the critical reception from SimCity in 2013. Olympus was said to be in development since 2008. The aesthetic and many objects from Olympus were reused in The Sims 4 base game. Sims of other players could be identified by a blue Plumbob over their heads, which turned out to be Olympus' signature feature.
