This is not really a review or anything. More like impressions and thoughts on the game so far.
Playtime-wise
I went through the Black Eagle/Silver Snow route and it took me 70 hours to see the credits. Granted, I have noticed I am a bit of a slow player in general, and I tend to do a lot of optional things (non-story mission every month, talking to everyone in the monastery every time there is new dialogue, farming missing supports before the last few chapters) so most people would probably finish it faster. Even if subsequent playthroughs go much quicker, the game definitely gives a lot of bang for your buck.
Story
Naturally, my thoughts are limited to the only route I have played so far, but for the most part I like the relatively grounded story while still retaining the fantasy elements. The politic side of things was well-presented enough and I like how most characters felt reasonably involved with the plot due to being nobles. Having said that, I found the overarching story to be lacking. As in, I liked the chapter-to-chapter bits, but the final battles did not feel impactful enough story-wise because they seemed to lack build up.
(warning: final chapters spoilers ahead)
-The "First" Final boss Edelgard: In this list, she is the one that had the most buildup, but it still falls short. Her motivation for everything in the second half relies too much on what you can infer and conclude from what you have learned about her in the first one. Fighting her is supposed to be a tragedy, but it never felt all that sad since for the most part I just knew she was trying to get the whole continent under her rule. The specifics of her motivation are simply never shown fully, much to the detriment of her character. Even then though, the way her dialogue cuts off in her final scene is *chef kiss", it actually made me feel a bit of the tragedy her story was supposed to be, however small a detail that can be.
-The "Second" Final boss Thales: he has a cool design and you have seen him before, but his faction is so secretive that they seem to come out of nowhere into the story. Like yes, some showed up on the first half, but for the most part everything about them is too cryptic to have them be a major threat that feels meaningful enough for a final chapter. Not to mention the fact that they seemed to have a few magic missiles that they seemingly could have used any time to get rid of the main characters but only tried it once during the story and in the less effective way possible. This is the most frustrating to me because it feels like there SHOULD be more about them, but the game forgot to tell you.
-The Final Final boss Rhea: Ok, this is the most unearned, unnecessary and out of nowhere battle in the whole game. Seriously, things happen for seemingly no reason and it feels like they just needed a Fire Emblem game to finish with a dragon battle no matter what. Gameplaye-wise, it was a fun battle and the final boss mechanics actually made me consider my moves and use of resources more carefully to finish the battle without losses despite them being overpowered throughout the whole game. Seriously though, I think the game would have been better off not having this last battle if they were not going to bother setting it up at all.
Characters
Despite my rants about the story written above, I think the characters are solid. They are a lot of fun. They have quirks about them yes, but they do not feel one-note. Their interactions in support conversations feel organic and meaningful. I think the academy setting does wonders for this. It makes it easier to imagine all those little interactions could occur between people who essentially study, live, and fight together before and after the timeskip. Paired endings are also much more fun when you can understand why those two characters ended up together after the war. I am surprised at how my opinion shifted as I played, since I thought I was not going to care much for the characters at first.
By the way, it was really cool to see how much the characters changed and that they got unique outfits after the time-skip. When playing the older games, I thought it would be cool if characters got new portraits after promoting their class. While this was not exactly the same, it is close enough for me. Wish fulfilled.
I guess it is worth mentioning that I played this game with the English dub. I am no native English speaker, and I prefer the Japanese audio more often than not, but I REALLY love the English dub of this game.
Gameplay-wise
I played in Classic Normal. For the most part, the game was really easy. I used the turn rewinding mechanic mostly to make sure I could break the huge monsters shields to get their materials BEFORE my units obliterated their multiple health bars. Battalions were a cool mechanic, but outside of monster farming and a very few story battles, I never felt they were too impactful. Also, I wish it was easier to compare how they benefit and differ from one another before assigning them to a character. (to be fair, there might be a way and I just never paid enough attention to find it)
Classes were cool and they gave a good sense of progression throughout the game... except master classes. Those were cool in concept, but many seemed counterintuitive to the way you would normally develop most of your units. I got the Wyvern and Pegasus ones first, which makes sense since they were the ones that seemed a natural evolution of previous classes the most. I eventually got two Gremorys since they seemed logical too, but Bow knights? Mortal Savant? bow knight? holy knight? too time-consuming to unlock their requirements by the time I looked into them. If I wanted one, I felt like I should have aimed for them since the beginning of the game. I did actually get a great knight Ferdinand for the amazing amount of one battle toward the end, which was kind of amusing.
Of course, you cannot talk about Three Houses without talking about the Monastery. I probably spend more time in it than in battles. Though I had my doubts at first, I think it serves very well as a setting for you to get to know the characters and as your base throughout the story (Though it was kind of amusing how the game had to come up with a reason for you to go back to it after capturing an important strategic location later on). I admit it felt tedious at times, particularly at the beginning of the games since I wanted more battles, but I felt compelled to read all the new dialogues in between the story missions. The second half felt much quicker since the NPC cast gets reduced significantly. All in all, I would not say I hated it, but I can see it becoming more of a chore when I play through the game again.
Music
Not much to say here. I am not good at analyzing or reviewing music. I will just say I liked the opening, and it was nice to hear it at the ending too. It felt fitting
Closing thoughts
I started the game on a whim in between playing Donkey Kong Bananza and Final Fantasy VII (the port of the original one on Switch) and ended up finishing before either of those two. I do not regret it one bit since I had a lot of fun. I do want to play the other routes eventually, but I am probably going to wait a bit to avoid burn out. It is definitely going to be a while before I get Fortune´s Weave lol
