Honestly the best gacha I've played in my life simply because you can build whoever you want however you want

Birthright: The worst of the three gameplay-wise, there are no units that stand out from others except the royals, who are all broken as hell. Japan-inspired classes in Fire Emblem is kinda neat though.
Conquest: honestly a good experience, I would recommend it to people getting into the series. Fun units, but weak plot.
Revelation: no

Looking back on it, it's kinda meh. Lots of unresolved plot lines, a lot of underused characters in the story, wonky writing due to the four possible perspectives...
Gameplay is quite fun though

Most of the vanilla game sucks, as the writing is kinda wonky and the characters don't have nearly as much personality as the ones from older games.
The third semester though ? Awesome. The entire game should have been like this.

A good game, but most of those that came after surpassed it

A very pretty game with a kickass soundtrack.

Awesome game, and a great way both to start the series and to breathe between 5 and 6
