The Elder Scrolls games have a pretty awesome world too...

The Lord of the Rings
Berserk
the Elder Scrolls ( with Mods lots of it. Especially Beauty pack xD )
Almost all Final Fantasy Worlds
The Vision of Escaflowne ( I think the world is Gaea/Gaia )
Trinity Blood

These are some off the top of my head.

Tlön, Uqbar, Orbis Tertius
try to imagine a fictional world like ours where stories and references to another fictional world abound to the point where the fictional world merge and overtake the real world . 😀

Harry Potter
Sailor Moon

The Pokemon universe!

Quote from ExzyruSxxx

The Pokemon universe!

I DEFINITELY AGREE! but its gonna get boring after a while.

D'oh!

-One piece (pretty safe... emphasis on pretty). Plus it'd be awesome to have a devil fruit ability
-Mortal Instrument series (books) - eg. City of Bones, City of Ashes

• The Percy Jackson series (books)- Lightning Thief (love to be a demigod)
  -Nurarihyon no Mago (manga)- seeing youkai like nura and rihan would be... 😁
  -also who can forget Star Wars!

Shabump~

Aqua in Aqua and Aria
It's just so beautiful I wanna cry...

I'd have to go with the 'Forgotten Realms' world from Wizards of the Coast.
Massive word, many stories (a few computer games take place in this world, but there are many many books), an incredible collection of available lore, has allot of diversity (not just focused on one thing) of cultures, races and stories...

And, which is always nice, it's still growing and has an active community constantly contributing and keeping it alive.
