Probably my favorite FE game I've played so far.
Ike's a really good character. The nature of FE makes it so that it's pretty hard to have good supporting characters beyond just their vibes, but I do like this game's cast for what it's worth.
I liked the plot a lot less after Begnion. The magic medallion stuff didn't really interest me at all compared to the compelling themes about uniting different cultures and ending discrimination.
One thing that somewhat bothers me is how characters would be joining your army super late into the game. I get that people die but towards the end things start feeling really bloated and my army was filled more and more with characters that I barely even knew. Also, limiting supports is dumb. Even if you don't want to give out the mechanical benefit too often you still shouldn't put a hard limit on them given that a good amount of them have character backstories, and for some characters the support scenes make up a majority of their lines. The dialogue in general is really well written though.
