Worst to best
Fates (laughable stories on all 3)
Blazing Sword (good characters, but funny/dumb story)
Genealogy (such a boring generation 2, it loses its flame past part 1)
Radiant Dawn (part 1 = good, part 2 = great, part 3 = boring, part 4 = terrible)
Awakening (Good arcs 1 and 3 but all together just don't connect well)
Gaiden/SoV (I don't like the protagonists in the later arcs but the story works)
Binding Blade (dull protagonist is my only complaint)
FE1/3/Remakes (Simple but effective)
Thracia (The lore of Genealogy but with a better main character and story)
PoR (Great world building, nice story, great cast)
Sacred Stones (Loved the story, the villains and everything else except Ephraim)
