Well, I'm now finally playing Persona 3 FES (which arrived early, thank you Amazon.com) and was pleseantly suprised to hear a few vocal actors.
Dan Woren as Igor and Ikutsuki Shuji and the actor who did Vayne Aurelius in Mana Khemia: Alchemists of Al-Revis as Sanada Akihiko. I hope to hear more recognizable actors the further I play.
Why when they localize Japanese games the companies don't give the names of the Japanese characters in proper order (clan name first, given name second) is beyond me. The only localized game I've come across so far that gets it right was Front Mission 3.
