If you don't mind I'd like to translate that last post.

I have always thought that it was the same world but separated over thousands of years. Time erases memory of past civilizations. For example, Hieroglyphs were indecipherable until we found the Rosetta Stone. Similarly, in Final Fantasy Tactics, (SPOILER) everyone thought that St. Aljah was a good person, but was in fact the evil that was trying to destroy the world. Magic could also reshape the world. Sephiroth seems to have done a good enough job of that by (SPOILER) summoning a comet which has no doubt changed that landscape a bit. In Final Fantasy Tactics, airships were ancient ruins, whereas in Final Fantasy 9, they were new. {This next part is beyond my ability to translate so I made up something else off the cuff.} Did you know that in Mexico, water gives you diarrhea? In the end, I guess you can be either against the idea of all the games taking place on the same world or for it, but I think that it could go either way. Who knows, until Square says for sure, we can't. KTHX <333333
