Interesting theory, but be a bit logical.

Why would SE throw off their fans? I mean when we visualize a new number in the series we usually assume a new universe, world, environment, cast of characters, etc unrelated to the other Final Fantasies. While there may be similarities in the looks and environments, it doesn't necessarily mean it is. Besides, SE is pretty informative when it has a sequel, prequel, whatever relating to a title already released, if this title was related to the FFX universe then I'm 100% sure they would have mentioned it, or have it labeled X-3, or at least call it FFX: The Blah Blah Blah. I mean look how informative they were with the VII series, it's not like they called FFVII:Advent Children, FFXIV, or FFVIIoC, FFXV. Logically a company wants to keep their fans happy and deception ain't gonna pull that off. So in my personal opinion, the new number represents a new universe. If it does have Any relationship to any of the other Final Fantasies then there's probably a dramatic time difference or the games located in a different planet/galaxy/dimension, call it what you will.

As for the issue with FFXI relating to FFXII, you have to look at how SE set it up. XI is different from what we've seen, it's an online rpg, it's a totally different experience then what we typically encounter, I mean there's actual human interaction going on (we've never seen this in the FF series, at all). SE probably found it appropriate to have the player experience the same universe in a single-player aspect, [img]/xxx.gif[/img][img]/xxx.gif[/img][img]/xxx.gif[/img][img]/xxx.gif[/img] I would too.

Although I ain't sayin' you're theory is totally incorrect, I think it's kind of deceiving and illogical if it is true to the fans. I'd be kind of pissed if I found out XIII takes place in Spira again, c'mon now, we need something new and fresh already. I personally think SE is running out of ideas with character looks and concepts, it's kind of ridiculous. All the main characters are starting to look the same or act the same. I mean Cloud and Squall are practically identical, Seifer and Sephiroth. Visually they look awkward too, the XII main character, to me, looks like a mix of Squall and Cloud. I'm just babblin' on though.

Just my two cents.
