Fates felt more of a tactical waifu simulator than what Fire Emblem is actually supposed to be, a challenging srpg series. The writing and story was horrible in comparison to previous titles, the cast was bland was hell save a few good characters, and Corrin was the STUPIDEST protag to ever waltz out of the series. They spend the whole game bumbling around and having their siblings be like "aww it ok we'll fix ur mistakes!!"
Also, there was no reason for the game to be split into three. Not at all. It was a cheap ploy at a cash grab, and Revelations is the "canon" route, so what was even the POINT of the difficult """"choices"""" they had you make? It made Conquest and Birthright literally shitty AUs that had no purpose of existing because they weren't even canon.
