If anyone needs a British accent, it's Steiner. There's no such thing as an American Knight.

You should do casting calls or something. You know, get a bunch of voices together and figure out who should do who based on them. Things will sound much, much better that way.

Also, you should start simple instead of doing the whole thing from the start, if that's not already been mentioned/figured out. Just do a "in a nutshell" thing. I remember FFVIII in a nutshell, which featured one or two EoFFers. That was awesome.
