UPDATE: SimGuruDrake has confirmed that the concept art below is very old. She has also confirmed that this world is not going to be released.
It seems that there may be a new world in the works for The Sims 4 which features a beach area. Artist Michael Bierek posted some concept art of a beach area called Rose Beach. For those who don’t know, Michael Bierek works for a company called Massive Black who were previously contracted by EA to work on concept art for The Sims 4. Nothing is known about this new world and whether it will be something patched into the game or included in an Expansion Pack. Until we hear anything official, we will file this under Rumors and Speculation.
Many Thanks to Sam for the tip!
