This argument could go on forever...

I got to thinking well...
FFI did have time travel and in FFVI the world changed in the course of about a year. Maybe they don't all take place in the same world but what about the same galaxy (kinda like Phantasy Star)?
The Mysidians could have used the Great Whale to go to another planet (ie IV) and Kain was smuggled onboard?
I know I'm reaching but whose to say Square won't try some similar scheme to get the green?
I think the name Highwind is to
reference that they are Dragoons.
Also isn't the Tower of Babel in just about every Adventure Game/RPG out there?
