Not sure what to write on this game since my opinion pretty much lines up with the mainstream opinion so I guess I'll just mention some minor points that I don't see get brought up as often.

While the main story is overall pretty engaging I think it takes a bit too long to really get going. One of the main reasons it took me over a month to beat this game was that initially I just wasn't super invested yet so it often was difficult to motivate myself to play this.

I also thought it was a pretty weird move to give Dagger the Eidolons early on without letting her use them and just not comment on that until you're several dozen hours into the game.
Having this great power that she's too afraid to use because of the destructive power they hold is really interesting but I feel like it should have been mentioned earlier for it to really work.

The parts where you have to assign people to do things and have no hints whatsoever but doing the right thing gives some reward are so strange.

It's a real shame that a game with as many callbacks as this is localized so badly in some parts, especially the things that feel like they wouldn't have happened if the localizers had just like, played the other final fantasy games? Something like "Mount Gulug" or "Deathguise" is just really embarassing.
Though it was a bit funny that they're apparently allergic to localizing Marilith correctly.

The music is really good, maybe my favourite FF music yet? Though it's a shame how few unique boss themes there are and how often the game just cuts off the music very abruptly because a cutscene ended or something.

Overall a very enjoyable game!
