Heh, that is a fair point, there's just a myriad of connotations behind the genre of "incremental" that an action RPG doesn't necessarily meet, even though it absolutely satisfies the technical definitions!
I'm not sure if the NG+ option would change where this game stands for me, genre-wise, although it's certainly interesting to try to think of *why* it doesn't change anything, and perhaps I'll end up with an answer that helps me figure out my design crutches and biases, but for now I unfortunately have to say "I don't know why exactly I have this opinion/stance, just that it is the conclusion I'm currently drawing".
Either way, I can at the very least say it was a fun game, unless someone decides to contest the definition of game or something XD
