Messed around with this a bit. Got through the first battle. The aesthetic is gorgeous (not just the graphics, the character design is aces), the gameplay is fun, and the writing is... well, it's bad. It's not Fates, but it's not good. The worldbuilding strikes me as incredibly shallow, the "political" conflict, doubly so.
The core conceit - that there's three nations on the continent (why do all of these JRPG medieval Europes have 2-3 countries at most?), each of which has one resource the others cannot do without, is just... it's dumb. That's a recipe for an interesting Cold War premise, not an ongoing open conflict - they can't afford to go to war with each other, they need the others too much. So the whole thing feels kinda hackneyed from the word jump. The dialogue is appropriately old-timey, but not nearly as strong as it could be. VA work doesn't help with that. Honestly, given that this is the studio that gave us Octopath, I shouldn't really be surprised that the story is... less than promising.
Still. The gameplay is great. It's adapted some mechanics from Octopath in a very interesting way, and there seems to be a lot of nuance to the tactics. I could see myself putting a lot of hours into that. And it's very pretty. I just wish that the writing was better... maybe the full story will pick up somewhere down the line.
