That's true, but as far as we know each Zelda takes place hundreds, possible thousands of years in between, whereas in Ivalice FFXII, RW and FFTA2 all take place very close to each other in the timeline, to the point where actual locations and characters make important appearances or mentions. Anyway, I'm not as concerned w/ Zelda as I am with Ivalice. While there are similarities, Zelda almost Always takes place in the SAME kingdom w/ many of the SAME locations, whereas Ivalice takes place in different locations and mentions previous locations and events. While Ivalice may not be one long story, the events of each game seem to affect the entire region/world. I'm starting to wonder if Ivalice has become more of a world than a region as a new, 4th continent has been added.

Besides, I prefer continuity over just random stories in random locales. Even if it is a series of disconnected games, they are set in the same world, with consequences of the actions to each game being felt everywhere.
