To be honest,
this is a game done with the RPG Maker where there is a whole bucket of gameplay. It is about playing MANY hours and there is a content that the whole grinding won´t be wasted in the "end" of the game.
Getting this play for a RPG Maker game is very spezial and mor as positiv, so when people write "terrible game" then they mostly just want to salt around or are tourists.
Sure the part 3 story could have more but mostly it is alltime so (Chaos Black Alice storyline was for me a bit empty).
But to be honest, other big games lost the story input the last years more extremly for example pokemon.
PS: For the people afraid of Mimics and Pandoras,
when you are afraid than your team is too weak

But no jokes Mimic and so are the best way to farm Jobpoints and Big Medals at least for the mid game. Don´t beat them is a big waste of farming.
