There are Sims 3 custom worlds, and you can find them on a variety of websites in the Internet.
custom content is legal for the sims 3 and any other game,unless it breaks copyright laws
You can find custom content on various third-party websites, or by downloading pre-made Sims with custom content from the Sims 3 Exchange.
Happy Simming! <3 FSC

I've not seen escalators for TS3. I would try some of the custom content sites and request that one be made. Mod The Sims is a good place to start...they have good creators who are willing to do requests.
You can have one, but custom content is required.

This is how to add custom music if you play sims 3 on a pc: Go to: My Computer>(the drive you installed Sims to)>Program Files>Electronic Arts> The Sims 3>GameData>Shared>NonPackaged>CustomMusic and drop files into this folder. They then should play on your sims' stereo, under custom music :)
The only way a sims can change its muscularity in any sims 2 game is if you download skins from custom content sites like ,mod the sims or the sims resource. this is only possible in sims 3 hope i helped
