Yeah, I know PSO2 was made before such games as TellTales' Walking Dead, Until Dawn or Hogwarts Mystery, games that have elaborate decision making that alters the outcome of the story... it's just in PSO2 story I just felt like I was standing there most of the time like a wooden cutout. That whenever the story asks me for my oppinions or decisions it give me two responses to choose from that have the same answers.
I believe when it comes to video games that offer you to play as a customizable character, complexity is required for lack characteristics. That way the player can shape that complexity to how they wish there character to be, thus be customized on the inside as well the outside. The story can still keep them in reasonable bounds such as they have to be an ARKS operative, they have to be good guys and they have to be the Guardian. But it be interesting if the players can actually end up making various NPCs (such as each Council Six members, or the NPCs that start orbiting around you) either like, resent or hate you, or the story will offer alternative objectives due to choices you made.
Still doesn't matter now given PSO2 is fairly dated and I doubt New Genesis will make you choose between Aina or Mannon to go to Space Prom.
