Welp, since /qa/ is dead, I'll just leave this here.
>>1247756>>1248367>>1248838It's an anime, albeit it shares none of the tropes within most anime, since the source material was a set of novels not a manga. The anime chronicles Yang Wen li, a prospective commodore in the Free Planets Alliance's navy and Reinhard Von Müsel, likewise, but in the Galactic Empire's navy. Yang Wen li, working within the corrupt FPA, seeks to uphold the republic, even if it's at the behest of those engaging in corruption. While the more ambitious Reinhard Von Müsel seeks to overthrow the entire Galactic Empire to establish a more just society, while ridding the society of the nobility whom have no skill other than gossiping. Neither Yang Wen li or Reinhard Von Müsel are the "bad guys" in the series, rather both are altruistic and hope to end the century-long war, yet both will end up taking arms against each other inevitably.
The main series is 110 episodes long, however there are 52 additional episodes which you can either watch before or after the main series (I would suggest before, since it gives the background behind how Yang and Reinhard got to where they were in the beginning of the main series). Since LoGH was an OVA it had none of the traditional time or budget constraints of most anime, which means that production quality remains high throughout the entire series. The soundtrack of the anime is entirely composed of classical works, which makes for awesome battles and tense political scenes. The anime goes very into depth into nearly every character (of which, there's more than 20) and faction, and politics is given just as much, if not more importance than the battles.
If you're at all interested in politics and/or military strategy, then you'll find LoGH very interesting and entertaining. However, if you find alternating settings, large casts, and long story-based arcs boring or confusing, then LoGH will be the same for you.
However, if you wait, Production I.G. is making a new version this year.
