Since all the games are related maybe the most ancient era (Centra) is before the times of all FFs.After all it has a medieval touch.
Ok, FE, before you come back to your own little world and start being different, let me remind you that all the FFs are not related. They happen in different places and different times. Quoting:

Final Fantasy was made in 1987 by Hironubu Sakaguchi and was actually made as a farewell "present" to Square Co., Ltd. He felt that the gaming world was going in circles and that no-one wanted to take any chances with a new type of game. So he decided to quit the buisness and start a new career doing something completely different, maybe become a fisherman. But before he could do this he needed to prove to both himself and the rest of the world that the age of groundbreaking games were not over. He sat down and worked over a long period in secret on his last project ever. His last dream. His Final Fantasy. And so the name was created. Final Fantasy was a single man's last wish for proving that new things could still be made. And so far every single FF game has improved the gaming world in ways no-one could imagine. Every game has introduced something new, either in terms of graphic, gameplay, voices & music, engine... You name it, Final Fantasy has always been the first to go new ways. And that is how it should be. The moment Hironubu Sakaguchi feels the games are copying themselves he is going to quit and become a fisherman.
Now this might seem irrelevant to you, but the game are different as are their worlds. Clearly, FF6 and FF:Spirits Within are different worlds. One takes place on the Earth, the other in a fictional world. Though the planet might have come through various era's the landscape would still look similar, which is not the case in any off the FFs. Compare the maps:

Now a map of our Earth and thus FF:SE:


Now please, tell me that they all look similar? Or maybe you want to say that the earth has changed during that time and that the periods between the games are so long. Well:



What you see on the picture are continental plates. No matter at what age of the development of earth you go, you'll be able to more or less see them on the map. Now, all FFs have different maps and the plates tend to be different as well, so no, I do not think that it is the same planet.

No ideas of interplanetar training has been introduced in either of FFs, but FF:ENDLESS NOVA, which is not made by SquareEnix, and thus cannot be counted as evidence. Thus, your wrong.
