Zanarkand's neighbours (spoilers)

[Tavrobel]

Shouldn't the people of Zanarkand notice that they're the only city they have any contact with? Especially a city that has a blitzball franchise. :P

And if I were a resident there, I'd be pretty pissed at Tidus for halting my existance at the end of the game without my permission.

It's like the Matrix; they don't know that they are the only ones because Yu Yevon probably had the Fayth dream that the people did not have a desire to explore the outside world. Even Tidus at the beginning of the game thought he had traveled through time instead of being in a different world (world meaning DZ, not world as in Spira).

Also with the Blitzballers, if you listen closely, Zanarkand has multiple teams, including the Duggles (the opposing team in the intro FMV), which are in Zanarkand conference C. I would venture a guess it works like NFL, but for one city.
