Just finished and....(spoilers)

[Lexy]

I agree that unsatisfying is the best word to describe the ending. I felt the same way, that I put all this time into this game and then:
1) The final dungeon and battle were ridiculously short and easy
2) The final after-battle ending was very short relative to the other FF's

I think the story came together really well by the end, but after putting 150+ hr into a game, I want what most of the other FF's gave...a long ending that shows all the main characters. I like that it left things very open, but at least give us more footage. And another complaint...the pop songs have got to stop. The dumb song felt so unrelated to anything else in the game.
So, I agree that the ending was not very good. Given that everything else in the game is insanely good, I expected a sweet, epic ending. It was just wierd.
