There are a lot of games I've never played but like their stories/artwork/other aspects, and Asura's Wrath is a big one in that department.
Mostly, it's because it's more or less the same tone-wise as Gurren Lagann's more serious moments (and I'm pretty sure I'm on the record as a big fan of Gurren Lagann in spite of its over-the-top fanservice) and like Gurren Lagann is a very loose adaptation of the angry, awesome prologue chapters of Journey to the West with a rather different ending. (I'm not going to go on a rant, because I'm well aware I've got... let's call them "loud opinions that nobody needs to hear," but some important precepts of Buddhist philosophy make me angry, angry the way that lapsed Catholics and hard-edged atheists get about Christianity.)
That "basically serious Gurren Lagann" tone just keeps me coming back to watching playthrough videos, over and over, even if I can't understand the dialogue.
Case in point: The below video, which gets simply amazing around 6:21. (I'm sorry I've never figured out YouTube's embed code trick for queuing up a specific part of a video, but honestly I'm not sure the modern embed code even has that option and figuring out the old code is probably kinda hopeless at this point.)
Who really needs to know what they're saying after that?
Also: Is it strange that I find it completely adorable that Asura's basic motivation for going on his epic pantheon-breaking rampage is to punch the guys who made his daughter cry? He makes that guy from that other pantheon-busting game look like a jerk and a pansy.
