How is it not? Didn't include Souls either but I don't see some of you mentioning that?
Its pretty simple. They are JRPGs in a literal sense however there appeal is very different. If someone was to ask for JRPGs on the PS4, often they will be referring to stuff like FF, KH, Tales, Persona etc than Bloodborne or Nioh. You can say, wait those are all JRPGs, but the association of JRPG to linear, story driven and character focused adventures are undeniable and is the very reason the whole what is a JRPG discussion even arises. Its not going to change.
For a holiday month, if little change in the LTD and poor Japanese sales, it is a bomb.
