That anime looked really interesting, before I saw the mechs and space ships.
The style may be anime, but that's no TV show, it's Xenogears, a masterpiece RPG by SquareSoft. The story has no equal among video games, as far as I'm concerned, surpassing every Final Fantasy. katethegreat's rendition of "Bonds of Sea and Fire" is set to bits of the prerendered cutscenes - which are actually few and far between, the game's that long and involved.
While mechs (the game calls them "Gears") are involved in combat, it isn't Gundam - the Gears are part of the story, but not a driving force for the most part. None of the story takes place in space, apart from the prologue video.
Oh, I forgot to review, didn't I? 8/10, I guess - interesting mix of classical and rock elements, not your typical anime mash-up. Fun, but not my favorite thing in the world.
