I haven't posted here? Alright.
I'm a fairly long time fan. Played Awakening back in '14, played Fates at launch, have al three routes of that. Also own both FE7 (Blazing Sword) and FE8 (Sacred Stones), having completed both of those. I'm also currently playing FE6 (Sword of Seals), FE4 (Genealogy of the Holy War), and FE12 through translation patches.
My favorite game definitely Blazing Sword. Hector is best lord. As for the newer, more controversial titles...
Awakening is okay. Characters are good, but the level design is boring, and the plot is pretty bad after the first act. Especially the villains.
Conquest is fun, but the plot is utter garbage. Birthright is okay, but didn't do much with the formula. Revelation is also okay. I'm in the minority that think it was alright (most people though it was terrible), though it was kinda a missed opportunity IMO.
Edit: Also, Hector is best lord.
