I like the voice acting a lot more in this game. My only gripe is that (spoiler maybe..) (SPOILER)O'aka sounds REALLY stupid when he says his "Welcome to O'aka's!" bit.

And the Hypellos sound kinda funny too, like everything they say ends with a question mark. It doesn't make any sense. I really like Rikku's voice a lot. She did a really good job.
