NIER is far from perfect - in fact, it's decidedly below average at times - but for every sloppy design decision or hackneyed rehash there are charming and often unique aspects that are worth the investment.

NIER may have, like its protagonist, a rough life of solitude and constant struggle against the odds... or it could become a cult hit that inspires more like it. I think the first outcome is more likely since, so far, it's been overlooked due to a defiance of definition, an obscure story and an odd title.
