This is exactly the kind of thread I was looking for, My favorite custom world right now is The Wild, Wild West which was created by TS3 Creators’ Consortium. It's a beautiful world that is great for storytelling. The backstory is that it is a former wild west town that is now a touristy place. There's also everything you could possibly want in a world including but not limited to: saloons, bars, an adventure base, a martial arts academy and so much more.

There's some treasure to find and it's just a great set piece in general.
