I only recognised one voice actor in the English while playing, and that was Urianger - the voice of Balthier for crying out loud, miscast of epic proportions there. So few lines for such a great VA, and on top of that he would have suited Thancred so well (imo, obviously).

A quick glance at the cast lists I can find include several big names who don't even voice a named character (Steve Blum, Claudia Black, Nolan fricking North) while all the named characters I can find are voiced by relative unknowns. I find this mind-boggling, but can applaud SE for giving people who aren't "names" the chance to show their stuff.

What bothers me about the voice acting, however, is how terrible pretty much all the VAs are at English accents. They all sound like Americans putting on a bad "posh" accent, Minfilia being the worst of the lot. As a British person, it really grates.
