The game is getting a mixed reception. They marketed the game in the direct really badly. I am not surprised that people are underwhelmed by it.
From what I am seeing the gameplay seems to be an improvement over Fates (Which was also amazing). It is the content I am more worried about. Fates had a lackluster story with lackluster lore with a lot of hit and miss characters. If it wasn't for the gameplay that game probably would have been a lot worse. Three Houses ' s content is just a big question mark. I have no idea what the story is or how the characters are like. So, for now, I have no reason to be hyped other than it being Fire Emblem.
