I know a game story worked on me when the last part of it moves me a lot. I liked this group of friends and their roadtrip. The focus on their journey shadowed Lunafreya, ok, but it made everything more powerful because you do feel for Noctis. The DLC should have been in game instead but Prompto or Ignis story worked on me a lot.
Music wise, Yoko Shinomura did a perfect job.
The open world is pretty but there is nothing to do there unfortunately. It's the big flow of this game. No minigames just hunts.
But i loved it and it's not the bad game I heard about. And to know it ended Hajime Tabata's career while he took over Tetsuya Nomura's chaotic development is so unfair imo.
