Nah, man
It was a project forever in development hell that Square wanted to get out of the door no matter how complete the game was. Tabata's job wasn't even about making a good game, it was simply making a working product.
It wasn't a "concept" game, it was a "whatever we can do in order to ship it" game.
Nobody wanted more of that vision. They wanted Versus. Even with the DLCs, people were expecting more Versus mostly.
And at the end of the day it got waaay more than it deserved: a movie, anime series, 5 DLCs, a multiplayer mode, Royal Edition and etc.
Way more than better, much more deserving FF games got in the past
