Let's start off with the OST being unironically the best in the series. Reincarnation? BANGER. Feel? BANGER. Give Me? Labryinth? Dream Catcher? BANGER after BANGER. I literally felt more emotion listening Opera of Light then the "Everyone is Here" trailer. This OST gets played in the car, no exceptions.

This game is the epitome of "this just feels right". It got the perfect amount of quality of life features to keep me enjoying myself. The weapon upgrade system is not complex and easily usable throughout the story (unlike Fates). Combos in combat (taken from Persona) stays fluid through the story. Achievements aren't generic (Engage) and don't get tedious (Three Hopes). Also has a functional New Game Plus mode which I hope stays a standard in the FE series.

The characters and story don't fall short either. Each member of the main and supporting cast gets their time in the spotlight while staying relevant through the rest of the game. The mirages don't take the spotlight from the original characters but get used to bring out the characteristics in them (better than Engage's way). The story of TMS existing in the universe where Marth failed to destroy Medeus makes this more canon than the other spin-offs.

Overall this game has everything I could find enjoyable without any negatives. Full remarks.
