Here's what I think about the final team
Cecil - Johnny Young Bosch
Kain - Crispon Freeman
Rydia - Sandy Fox
Rosa - Stephine Sheh
Edge - Yuri Lowenthal
I'm massively in favour of Kain being Scottish. It's just really hard to have someone with a Scottish accent without them uttering Scottish words and phrases and I can hardly see Kain going "Aye pal, ye'll be deed within the minute." Or something equally as sinister during battle.
Ocht.
I have yet to pla this game. Final Fantasy III was great so if Final Fantasy IV is the same, mixed with voice acting it will be the best game ever!!!
Play Ten, or watch Advent Children dubbed, and you'll have a pretty good idea of what the voices will be. Heck, watch any dubbed anime for that matter. I can pretty much guarantee you a Steve Blum and/or Chrispin Freeman siting, using the same voices they use in every single thing they've been cast in before. Mmm, yay for variety.
Not my words Carol, the words of Top Gear magazine.
