Overall, it would be the old D&D Known World.
There is so much wacky and wild stuff to use alongside areas of more traditional fantasy trappings that make it a great place to run games in for any edition. I started running basic D&D campaigns there. I ran a GURPS fantasy swashbucker game set in Darokin, and now my current 4E campaign is taking place in Karameikos.
The place is so versatile. There are areas civilized enough to run an old school style fantasy campaign and other places that are perfect for a points of light campaign.
