Regarding comparisons between Killer7 and NMH:
I remember some people saying that while NMH is not a sequel to Killer7, it is its "spiritual successor", or somesuch. Now that I've played both (but haven't yet finished Killer7), I think that is an exaggeration.
There are definitely some areas of distinct similarities, like the graphic/audio used to introduce boss fights and the overall feeling that the creator must be a bit of a lunatic/excentric, but NMH is not nearly as dark or heavy as Killer7.
NMH is very tonge-in-cheek, with a lot of dark humor that is delivered with a wink and nod toward the gamer. It is a game about an otaku designed by an otaku, to be played and enjoyed by otaku.
