Fire Emblem is a difficult series, I don't know if you guys have heard

Get FE7 or FE9 next. FE11 is the worst from this millenia.

FE7 and FE9 are both awesome. Then FE8 is pretty great, but not as good as FE7.

 

FE10 is the best one.

FE6 is, frankly, far inferior to the rest of the titles.

Edit: Other than FE11. FE11 is the worst.
