Got to know it through the first western release, Fire Emblem Blazing Sword (the seventh one). It was my first strategy game, and, well, I sucked at it. I didn’t reset everytime a unit of me died, so when I was at the last chapter, I just barely made it to Nergal, and then the dragon showed up (Oh, and I didn’t know about Luna’s overpoweredness). I wasn’t able to beat it back then, still, it was fun, so I got myself Sacred Stones when it came out.
This one was easier, and I myself also got better at the game. Later, I replayed FE 7 again, and I couldn’t understand what was so hard the first time.
So I was hooked for the series.
I played Path of Radiance and Radiant Dawn as well, and I usually see these games’ stories as a unity, and it is one of my favorite stories.
I dropped Shadow Dragon somewhere around the tenth chapter, just wasn’t too interesting.
Played Awakening, overall liked it.
Sometime after Awakening, I researched a bit about the older FEs, and have since then watched Let’s Plays of Genealogy of the Holy War (one of the nicer stories), Thracia 776, Binding Blade and Heroes of Light and Shadow (aka New Mystery of the Emblem).
I am currently still playing Fates, and I think it is a nice game.
The only things I know about Gaiden is the stuff that Ghast Station talked about in his video “This is what happens in Fire Emblem Gaiden”.
I also looked at some stuff from the Romhack community through Youtube Videos, namely the Ragefest Contests, which were held by a Youtuber of the name of MarkyJoe1990.
