The managers chose to do this, and they chose a horrendous concept.
The developers just tried to execute, they also failed but the project was doomed from the start.
It's because they are not. An Rpg is not a jrpg just because it's made in Japan. JRPG refers to a very specific type of game, turn based largely linear. Final fantasy, Dragon Quest, Chrono Trigger, Octopath Traveler, etc etc. That's what most people think when you say JRPG and if so they would be right to say that they like or dislike the genre. This is a non issue as usual.
