I'm sad that the author gave up on this series in the end.
I like that Broken Blade is about the only contemporary mecha around whose main characters are actual adults facing adult issues, and not power-tripping teens. At least, I know no other example of it, though I have no interest in franchises like Gundam.
This series also had elements of political intrigue, military strategy… and I actually believe the author gave up on it only very recently. Till the chapter before this one, in fact, I could see the narrative lines flowing smoothly: Zess' plan to attack Mizram, the machinations of Orlando, even the Assam campaign was just a cog in the plot wheel. So I was shocked when I learned this chapter was the last one. It's like Yoshinaga decided to throw in the towel because this manga wasn't putting bread on the table or something.
I had grown to care for many of the characters in all sides here. This ending is wholly unsatisfactory.
Oh, well. I guess it's gonna be a while till another mecha manga that breaks the mould comes around. Bokura no: Ours doesn't quite make the cut as it's still teenagers and too philosophical.
