anouther shout out to Muv-Luv and not the crappy spin off's that the current anime is based on
of course how they would pull it off it gonna be hard... I mean 12-24 episodes of highschool life and wacky antics for set up and then another season for the aftermath? The problem with Muv-Luv (which is probably why the animators went for a spin off) is that is had two very different parts, both of which constitute two very different genres in anime which are of course, romance/comedy/slice of life vs mech/action (although there wasn't much action shown till the sequel)
one thing to point out... just cause its animated wont make it naturally inferior to original VN... although il admit this gets harder the better written the VN is... examples of an anime that I feel is better than the original VN it is based on Shuffle! Although like I said the VN is in my opinion.... poorly written the anime added enough tension and drama and delved into things a bit deeper when it needed to.
