I have to say, having just finally finished the last audiobook (well not counting that I have to wait for Part 3 / 4 of Case of Shinra, I'm really really disappointed that the audiobooks aren't a bigger attraction. The production is amazing and they are incredibly good stories on their own merits, even the FF13 -episode i- . All the voice actors you got nail their roles, a few personal favorites the voice actor for President Shinra (his voice gives me goosebumps at how dignified yet evil it is. Like a human Shere Khan), Barret (a voice actor so good he permanently changed how Barrett sounds in my head) and Nanaki (really nails the brief line of dialogue we get from AC and develops it into a very soothing voice.) They're all really really good though, the ones in the FF13 one nail the original voices. Also whoever is narrating these has a very pleasant, easy to listen to voice.
Gush over, just wanted to say I really loved them and am going to promote the hell out of the m to everybody I know.
