I agree with you Firefly that Squall's voice was too low. In the Final Fantasy games that have had voice acting I feel they have done a good job matching the voice to the character but in Dissidia I have found a few that haven't sit well with me - Squall being an example.

If Squall's voice wasn't so low I think that would have better suited him as the VA did a good job of portraying Squall's disinterest or lack of most emotion.
