Vanille's voice seems to go through these phases where it sounds absolutely horrible, and times where it is bearable. As soon as you make it to Pulse, in the second half of the game, her voice tends to be bearable more often.
I am really liking the more open world of Pulse. All of a sudden the difficulty sky rockets and the battles becomes pretty epic. Also, the story finally starts to get decent. Not great, but better.
EDIT: Also, Duo, if you see this thread, can you please move it to the Final Fantasy sub-thread? I barely noticed it now, didn't see it when I made the thread.
