In fact, chances are anyone who's savvy about English voice actors will recognize quite a few of them. Among others, Welkin is Dave Wittenberg (Kakashi), Alicia is Colleen O'Shaughnessey (Sora, Genis, and KOS-MOS), Rosie is Hedy Burress (Yuna), Largo is Fred Tatasciore (The Hulk, Saren, and additional voices in everything), and Faldio is Robin Atkin Downes (Luxord and Travis Touchdown).
Dammit! Now I have the mental image of the sevens screwing up, and Faldio shouting "TEEEEEEEEAM!"
Gregor is voiced in English by Roger Jackson, who is perhaps best known for voicing Mojo Jojo from Powerpuff Girls, and the Phone Voice(s) from the Scream franchise.
Perhaps the strangest of all is that April Stewart, the voice of Selvaria Bles, is arguably best known for her voice talents for practically every female character in the series South Park, of all things!
Murdock decided to join Gallian politics as the prime minister, who began to play both the Federation and the Empire and was executed on the orders of Tunnel Rat as he does not want to work with a double crosser.
If you've played Ace Combat 5, you should know that Welkin already has some experience saving his nation's leader - from a much more dire situation, in fact. And managed to evade Mobius One's wrath a few times.
What Could Have Been: There were plans to animate an impromptu wedding between Alicia and Welkin in the midst of battle atop the Edelweiss, with sketches of Alicia's thrown-together wedding dress. This was dropped due to time constraints.
The art book reveals that Darcsens were originally intended to be a race of cat people, and that the series in general would have much more fantastic elements, like the Empire possessing lizard cavalry and much greater prevalence of large superweapons. Edelweiss' original design looked more like the title tank Metal Slug.
The anime has the following trivia:
Fan Nickname: Faldio is often referred to as 'Superman' for his ability to do no wrong at certain points in the anime. Probably to make his eventual fall that much more shocking.
Maximilian has been called 'Maxi-pad' by people who are familliar with the game, due to the fact that he seems to be a mama's boy and well, just look at Lelouch's profile.
Early on, the series itself was nicknamed 'Kana Goes To War' on account of Alicia's various goofy facial expressions.
