So I just carrya discussion from the P4A2 thread about how the story mode would go here.
Now many pople would preferif the story would be like in CP, where there are only like three storylines. Where it might be good so that it doesn't feel repetive, it does bring up problem of character focus. For what I hear from CP story, there are quite a few characters who lack that much focus in the story (Tao, Arakune, Bullet, Amane, Azrael ect.). Because of that, I would argue that having multiple stories would be nice.
Also, on bit of spoilery side,
