Well, if you consider FFIV to be Earth, then just about every piece of literature ever.

Kingdom Hearts takes place in mostly Disney worlds and original worlds that exist only in the KH series.

Ehrgeiz only features FF characters.

Off the top of my head, and not including the tag "Final Fantasy" in the name, I can think of only one.

Bahamut Lagoon (released for Super Famicon) It has Bahamut so that makes it final fantasy, I guess.
