Okay, so I had about maybe an hour of the game. I am currently on Chapter 5.
First impressions:
Jeez, this game is downright beautiful. The story is pretty good so far as well.
I'm not impressed by the music yet... But that is the case for all Fire Emblem games. The music always gets progressively better.
Characters are extremely likable, relatable, and lovable. They are really well designed, well acted, and well written as well.
There is a ton of depth in this game. Just from the first real map this is clearly apparent. It clearly shows how much strategy is going to count, unlike Awakening. Everything is very well done!
Also, the game feels really good. The transitions themselves from battles just feels so good. It just does, all the little flourishes really help make this game stand out.
So far, I'm extremely impressed with the game.
