190 hours in and despite having a few trophies left and completing hard mode, I'm giving up on the platinum.
This game simply does not respect your time, knowing you'll spend hours retrying the same mini games, the same ridiculously overtuned fights, watching the same unskippable battle cutsenes, doing the same inane BS in every zone.
I've had enough, im done. Specifically, the battle challenging in both the arena and chadley you're forced to do on hard, but it's not even challenging, it's straight up asinine content designed to force you to fail and do it over since they don't tell you the enemies you'll face until you get to them, instead of helping you succeed.
I've completed so much of them and each one frustrated the hell out of me, and after I just killed a mindlfayer and quezalcoatl together, the game throws an insanely strong bandersnatch at you along with a king zu that repeatedly tries to one-shot-party-wipe you an, more often than not, succeeds because you have to delete the huge healthpools of its wings. Oh, and to top that off, not knowing I needed anti petrified means I'm guaranteed a loss just to have to do it all again. And that's how EVERY SINGLE HARD MODE "CHALLENGE" WORKS.
F this game, F Nomura, and F Square Enix most of all. People have better things to do, and I sincerely hope you don't use the sunk cost fallacy to waste so much of your time like I did mine. Make the healthy choice, just beat the game and wait for the next one. It's not worth it.
