But FFXV does still do that. It's supposed to be an insular story only involving Noctis and his friends, but then the game backtracks on that premise to show us cutscenes from other characters across the world.
They showed scenes from the movie when their city was destroyed, but Noctis wasn't there when it happened, so why show those scenes? Why do we see Luna receiving the letters from Noctis? He wasn't there either.
It's like anything else with FFXV, they kept changing what they wanted to do with it.
