Got the Design Archive at my local anime-based shop.
The guy who managed the payment asked if I played the game before. I was like, dude...
Enjoyed the stuff in there, especially the history of developing the game since it was suppose to be called "Gallian Panzers" during pre-production.
Also found a pic of the Ace Imperial soldier.
Take note that there are some minor errors with punctuation and all as I've read more than one half of the book already.
