I got the Platinum trophy for Final Fantasy XV a week ago but never wrote up my thoughts on the game, so I guess I'll give some quick impressions about it here:
I love the game, but I think it's a mess. For every strong point the game has, there often seems to be a weakness that comes with it for me. I liked the combat system, but I didn't like many of the boss fights in the main story. I liked most of the soundtrack, but I didn't like how some of it was implemented in the game. I liked Noctis, Ardyn, and the relationship between the party members, but I still thought they could have used more development and the rest of the characters fell flat for me. I liked the general concepts of the story and thought some individual cutscenes were well executed, but I thought the plot was poorly told and most of those cutscenes felt like payoff without much prior buildup. I liked the tone the game went for on the second continent with the train but felt that section was rushed from both a story and gameplay perspective. I could keep going with more examples but anyone reading this probably gets what I'm trying to say.
While I was playing the game, the pros definitely outweighed the cons for me, but I can't help but wonder what the game would have been like if it released a year later. I really get the impression that the game was rushed out the door and Tabata's team didn't have enough time to complete the game they wanted. Granted a lot of my story issues with Final Fantasy XV were even more prevalent in Final Fantasy Type-0 so it still might have had a messy execution if it got an extra year of development time.
When asked about Ifrit's role in the story and why he decided to unleash the Starscourge after falling out with the other five gods, Tabata answered "Sorry, I don't know the details".
I'm really not sure how to respond to this.
