Nice project, I remember hearing about this a while ago on the forums. It'll be fun to hear voice acted 1.0 scenes.

My one pressing suggestion:
Moogles, beastmen and any other species that don't speak Eorzean (English) should NOT be speaking it. In other words, have Moogles just use their "kupo" sounds from the game and rely on subtitles. Besides making more sense lore wise, an important instance this would come into play is when Minfilia can't understand the Sylphs and need you to translate. It would be weird if the Sylphs spoke English only to have Minfilia ask you to redundantly translate it into English...

Also, whoever did the moogle voice in that video should be doing Papalymo!
