So unlike you to quibble over pedantic lexical details.
Shall I make my point just that little bit more clear?
TSW posessed very few of the supernatural-based fantastic elements commonly associated with the FF games. It DID posess strong sci-fi based fantasy elements, but I prefer to distinguish science fiction and fantasy from one another for purposes of comparison.
I think of Star Wars, for example, as both science-fiction and fantasy, due to the blend of elements.
