I've always been much kinder to NitM than most, I think, and I believe it was well on the way to accomplishing something great. Most of the extra features are welcome additions for me, and it's merely the rushed execution I take issue with. For instance, while I think the new Richter sprite looks pretty bad, I applaud that they had the sense to question why Richter is still wearing the same clothes, especially as he's shown in the arena to be wearing his new dud prior to that fight, also implying that the Alucard Spear (which I think just began as a mistranslation of "Lecarde Spear" as the names are phonetically similar in English -- maybe Nagumo can weigh in) got its name by being, at one point, a spear wielded by Alucard.
I think the PSP "Director's Cut" of Symphony in DXC should have finished what Notcurne began, polishing up the Saturn version's additions and elaborating where necessary.
But alas!
