I cleared a while ago and might have spent too long digesting this one, but let's see what I can cough up.
WoL dialogue choices (MSQ clear)
I second the feeling that Wuk Lamat stole all my lines. I get that she needs someone edgy to play off of to seem more idealistic, really not thrilled about it being me.
Also, when Gulool Ja is asking the WoL about family, I wanted to outright namedrop the Scions or at least mention something to the effect of found family (given the direction he was about to be taken in), but it wouldn't let me. Endsinger did happen, right? What's with the aloof card?
That Final Zone
I think some variant of Memoria was inevitable. Where FFIX's was the heart of the FF multiverse (!?!?) and included some surprise bosses from earlier games, this one was trying to serve FFIX nostalgia except, as many times as I've played that game, I don't actually remember riding a gondola. That definitely happens in Fantasian, though.
I liked the plausible deniability gondola date. G'raha has no way of knowing this, but the Exarch's timeline did actually survive, but it was still nice that he was around to point out the elephant in the room after seemingly ignoring it through Endwalker.
I could have lived without Amaurot 3 as the final dungeon, though. It's a good recipe for a setpiece dungeon, but I miss the sheer spectacle of the Aetherochemical Research Facility.
All that grumbling aside, I really like Sphene. I feel like the story is usually pretty naive with how it throws about phrases "at any cost" when there's not much cost to be paid, but the entire Alexandria arc goes there. I think she might have actually improved on FFIX Garland by having a slightly more tangible objective than weird metaphysical terraforming. An Ascian was definitely involved in the groundwork here, but I'm curious how and why it got cut short. To be continued in 7.X?
Good Boys All Around
Like, seriously, though. Did the NPC team wake up one day and suddenly remember that Hyur boys are cute? Between the Viper storyline and MSQ post-95, I ate really well, but had no idea any of that was going to be on the menu. That's on top of Bakool Ja Ja earning his card and keeping it, and the surprise Gulool Ja we didn't even know existed.
I was totally expecting Zekowa to live up to his character archetype (the "young gun") and win the duel but die anyway because his opponent was using live ammo, but he circumvented that possibility entirely by drawing faster and shooting the gun. We're not in Heavensward anymore, Toto.
I'm glad that extradimensional lookalikes aren't limited to Rowena and Gerolt.
Shepetto... just kind of exists? You can check in on him after certain events and his position and dialogue changes, but I still don't know why we have a unique face model on a character with only 5 lines in the MSQ. That entire settlement was strangely underutilized.
Overall, I'd put this one around Stormblood tier. Good, but not the best. I think it knew it had the thankless task of being a breather episode after Endwalker and did the best it could within those parameters.
