Arda is my favorite fantasy world, without a bloody doubt. I am a Tolkien fanatic and will forever be one.

Halo universe is also one of my favorite universes; primarily because I adore the Halo series, games and books.

I do have to give credit to the Elder Scrolls universe, since it is very cool to have a Middle-Aged theme world with multiple races.

The one universe that will always be with me (besides Halo and Arda) is the Multiverse of the Magic the Gathering books and games. It is primarily a fantasy setting in its truest sense and it does draw on many different sources for its individual planes. After all with Planeswalkers, the story itself is damn good!
