Do you have any concept of how not to make a baity, old man-like post?
Nostalgia is the worst. It blinds people to hideous faults and makes them look down on modern games. Guess what SNESers out there: Xenoblade Chronicles > FFVI, Wind Waker > aLttP, and Galaxy > wait World is still amazing.
Never the less, stuff like abhorrent OoT nostalgia has lead to Twilght Princess's lack identity.
And about the first part? Awakening saved the series whether you feel like whining about it or not. SD and 12 may have met the mark, but they still wouldn't inspire confidence. Your favorite is Shadow Dragon so I think something's messed up here
also it's atrociously condescending to imply that casual mode is a bad thing. Elitists like that kill the series. And "an anime you can live in" is a terrible descriptor. It means pretty much nothing.
You are probably actually the worst type of Fire Emblem fan. One who accepts no change and is so stuck in their ways that they'd rather others suffer so we can go back to boring FE7 land.
