People discredit XV because of it's rushed development towards the end of it's dev cycle and it's overall turbulent lifespan even after release but, in it's final form as of when I played it in 2021, I can confidently say that XV is one of my favourite Final Fantasies and games of all time. The game's strengths really lie in it's character's development and relationships, especially between the main four, and does an incredible job of depicting realistic friendships with such steep power dynamics as those between Noctis and the rest of his party. I knocked off a star due to the gradual decline of the overall story upon reaching the train segment and loss of the open world, however, there are still some strong story beats in the later parts, especially regarding Ardyn, and so this doesn't destroy the game overall by any means. In conclusion, I see Final Fantasy XV as one of the most overlooked and underrated mainline games in the franchise that was screwed over by an incredibly long development time and a rushed release.
