Maybe I'm missing something and this is just a convention I'm unfamiliar with because outside of FFXIV and, like, Animal Crossing I don't really play videogames, but what is the "+" in NG+ if it offers no rewards or benefits? New game "plus" would seem to imply that it's "over and above" simply starting a new game, no? I don't necessarily feel strongly that it should/should not have any *specific* rewards, but it seems like there should be...something? I love the story too, but not enough to do it all again for no reward(s).
Happy for the people that wanted it though!
