So after finishing the game, I think I finally feel what people were upset about after XIII.
For as twisted and convoluted at XIII's story was, I at least understood the goals and antagonists from beginning to end. The characters made some decisions that pissed me off, but at least those decisions made sense in the story's framework and led to something.
XV feels like things just happen semi-randomly and stuff is completely unearned. Why did Ardyn need to kill Luna in the first place? Why was it presented so unceremoniously? Why even "Luna?"
There was nothing in the game, thematic or otherwise, that necessitated changing her name. "Lunafreya" just felt like Tabata saying "This is mine now."
I honestly think XIII has a better world and overall plot than XV, but XV's open world and combat system blows the Paradigm Shift system out of the water. When you're just wandering the world doing hunts and bashing heads in with your bros it's on of the greatest games ever made, but whenever the story creeps in I just get a headache - and I have a pretty strong stomach for confusing fantasy bullshit.
The seams of where this was tied to the Fabula Nova Crystallis legend/mythos are so, SO obvious, too.
There were so many times in the story where the character would talk about "gods" and I'd be like "Oh, you mean fal'Cie" and "covenants" and I'd go "Oh, like a Focus?"
Zombie Ravus was obviously supposed to be a Cieth, and his battle was hilariously parallel to Cid Raine's fight in XIII.
"Hey, here's this guy that's supposed to be important but we couldn't really figure out where to put him in the narrative so here, kill a boss version of him in a random empty warehouse location."
Noctis and Stella were obviously two l'Cie being given directly opposinn Focuses despite being at least passingly friendly with each other beforehand.
Stella's original intention seems to have been given to Ardyn wholesale, what with the pink Power of Kings and the purposed "street showdown" in Insomnia.
Versus 13 always felt like it was going heavy into the "Star-Crossed Lovers" Shakespearean angle, with "stars" being a pervading theme of the game, but XV just give us some passing formalities and glues a lot of disjointed ideas together.
I don't even understand what the "sleeping" motif is supposed to be anymore, with Luna asleep in the game's logo and Notcis "joining" her in the ending. It all feels random and unearned.
Around Chapter 8/9 I started feeling like I had theories about what was happening to the world, and none of them even remotely panned out.
The world remained much, much less interesting than concepts I could come up with off the top of my head, and that's sad.
I thought maybe there was an Astral/God tied to the sun and a corresponding God tied to the moon, and the Sun God/Goddess was falling asleep/getting lazy and making the days shorter, or something.
Instead we get some random star disease and the six Astrals doing random things because...reasons.
Hell, at least Titan and Leviathan got a "trial." Rahmuh gets a fetch quest and Shiva gets handed to you in the most hurried cut scene ever made.
"Gentiana...It's you! You're the Glacian!" is now the line that will always come to mind when I think "there was supposed to be more here, but we ran out of time and money."
