The tagline is pretty much a poor subtle attempt at marketing. Seriously.
Take Pokemon for example. The tagline for that early in its life is "Gotta Catch 'em All!", but nowhere in the game does it really address that to be a "Pokemon Master" that you have to catch them all (Nintendo actually makes it nearly impossible to catch them all).
So really, it's a moot point. The tagline means nothing as we already know what the hell goes on in the game.
Not to mention that Resident Evil (Biohazard) in Japan is advertised for it's compelling story and scary environments. Resident Evil in America is advertised for killing hordes of zombies. It's all marketing and appeal to players.
For the record, I was right. To anyone who was certain that Firion was changed to Frioniel, check the official site. Terra, Kefka, Golbez, and Bartz will all inevitably be the same once announced.
