[insert lots of bleeps about this bloody laptop and backbuttons]

Let's say they introduce Terra when we go into the Magitek mount quest line. Or Kefka when we finally venture out into Imperial lands. Or even a notable character related to the Crystal Tower or Eureka. All things which are possible, as a fan-service to previous titles.

What's the result going to be?

This, right here. Threads upon threads of people fussing over trivial things that in no way alter the scope and gameplay at all. Little events that distract players from the main story, like seasonal events, that could be incorporated into the world of Eorzea due to its aether imbalances and such. But that's ultimately all it is, seasonal events. Would you really quit over something so silly, such as that, something you arent forced to participate in?

YoshiP said that they would create a way to validate why she could and would be brought into our world; not that she was going to have some massive crucial role into the fate of the world. It's no different than easter egg hunts, or reindeer games, or building snowmen. It's there for fun, that's it. If it's not your cup of tea, then don't drink it.

Personally, I like it and I want to see what other crafty little things they can incorporate in and how.
