Square merged with Enix. Which means that Enix bought Square out. Square had lost a lot of money on its ill-fated "Square Pictures", and firing Sakaguchi wasn't enough to save the company.

Notice that Final Fantasy, the moment Square was bought by Enix, became a cash cow of epic proportions, giving fans exactly what they wanted. That was never what Sakaguchi's goal was. He was an artist; he had visions; he wanted to make a beautiful story about the power of friendship, goodness, and nature versus cynicism, techonological sterilization, and evil.

And then, Enix heard the fans, who missed the grandiose (if slightly pretentious) ideas of Sakaguchi and scremed such inanities like, "But Cloud's hair is sooo kakkoi".

Enter: FFX-2. Yuna with hot pants.

It's not that the games suck. They're polished, beautiful, and a joy to play. They are also under new management, and made to promote profits. Notice the team that makes Dragon Quest: they take their time and produce higher quality games than ever before.

Delita, you and I and a few others may weep for Bartz and co. saving the crystals and bringing kindness to different worlds (including our own), but... well, the fans have spoken.

Besides, they made Emperor Mateus so sugoi in Dissidia, don't you agree?
