Any Sims that you uploaded to the Gallery in the Create A Sim (CAS) demo must be downloaded from the Gallery in the full game. Households that are just saved to your Library will not be available in the full game until they are downloaded from the Gallery.
 
If you are not finding your Sims, it could be due to one of the following issues:

The CAS demo and The Sims 4 are on separate Origin accounts.

• If your demo and base game are tied to different Origin accounts, then your Sims from the demo will not populate into your base game Gallery.
• The easiest way to get your Sims is to upload them to the Gallery from the CAS demo. Then you can search for the proper Origin ID in Gallery and  download them in The Sims 4 on your other Origin account and download your Sims from the Gallery.*

 
The CAS demo and The Sims 4 are on the same Origin account, but the Sims were never uploaded to the Gallery.

• If the demo and base game are tied to the same Origin account, it’s likely that your Sims were not uploaded to the Gallery. Sims that are saved only to your Library in the demo will not display in the full game.

• The easiest way to get your Sims into the full game is to just upload them to the Gallery from the demo and then download them into the full game.* Otherwise, you can copy the files fromDocumentsElectronic ArtsThe Sims 4 Create A Sim DemoTray to DocumentsElectronic ArtsThe Sims 4Tray in order to “move” your Sims from the demo to the full game.

EA Help explained how to add your Custom music into The Sims 4!

Please note that your music file *must* be .mp3!

You can play your own MP3s through the radios in The Sims 4. Copy them into the The Sims 4Custom Music folder that corresponds with your genre of choice and tune your in-game radio to that station to hear your music.

Back in June, GamesTM published their preview of The Sims 4. There was an interesting sentence about a potential world in the game:

”We spot a drawing on a nearby whiteboard of a humble rural shack, surrounded by rolling farmland, livestock and mountains in the distance. Could the American frontier be another location in The Sims 4? Truong and his colleagues refuse to comment.”

While going through The Sims 4 Game Files, I saw this Concept Art of the World. It exactly matches with the description that GamesTM gave!

While continuing my scavanger hunt through the Pre-Load files, I noticed this interesting image!

What do you think it is? My guess is that it’s an early version of The Sims 4’s Map Mode! 🙂

While rummaging through The Sims 4’s Origin Pre-Load Files, I noticed this boxart of the game:

This means that after The Sims 4 is released, you’ll be able to upgrade your The Sims 4 Standard/Limited Edition to Digital Deluxe. The cost for SimCity’s Digital Deluxe Upgrade is 19,99$, so I don’t expect this price to be changed for The Sims 4 as well.

I was able to dig through the Pre-Load files of The Sims 4 and found a Concept Art of Oasis Springs! Check it out:
