For long years all I could play was FFTA, for I only had a GBA, didn't mean I hated all the Playstation ones, or the SNES and NES ones.
That's fine, but what a FF is called is really not up to us fans to decide. The creators do that, and we just have to go with it.
i'm not too worried about this inclusion, but it would be nice for FFXII to make an appearance as well (even though i don't really like them), just so that all of the current characters are in it (though, depending on how you see things, this may mean you also believe they should put in characters from XIII, which is a little bit excessive)
