The Sims Olympus

"Olympus" is an early prototype of The Sims 4 that was designed primarily as an online-multiplayer experience, similar to The Sims Online and The Sims Social. Development was started in 2008, but the project was refactored late into development as an offline singleplayer-only title that was released as The Sims 4.

It is not known why the online component of the game was abandoned, but it is commonly believed to be due to the poor reception towards SimCity (2013) and the subsequent closure of Maxis Emeryville. SimCity launched as an online-only title with some multiplayer aspects. This was heavily criticised by the media and by fans after the game experienced major issues with its authentication servers.

The general art style and many of the objects designed for Olympus were repurposed for The Sims 4 base game. The Tudor-styled world that can be seen in some screenshots is an early version of Windenburg (but spelled Windenbourg in the base game's code) which was eventually completed and released with The Sims 4: Get Together expansion pack.

In Olympus' only one Sim could be controlled at a time instead of an entire household, and Sims of other players would be identified by a blue Plumbob over their heads. A statue of a blue Plumbob appears as an object in The Sims 3: University Life titled "Into the Future" possibly foreshadowing the Olympus project, as well as The Sims 3: Into the Future. Having a blue Plumbob to represent other player's Sims is a concept that is reused in The Sims Mobile.

Various remnants of the game's original design can be found in the game files. The Sims 4 's game engine itself also contains features that are usually found in online games, such as instancing and server commands.

Leaked Images
Most of these images have been leaked on the internet by various developers that worked on Olympus and one officially through the Google Expeditions VR tour of The Sims studio. Some have also been found in the game files of The Sims 4.

Neighborhoods
Multiple screenshots of Olympus' neighborhoods can be found in the game files of The Sims 4. Some of the screenshots show a Tudor-styled world similar to The Sims 4: Get Together 's Windenburg, while others show a world closely resembling Willow Creek.
