I've never played the non-localized games and this one was the first to introduce the series to me, much like many other people, but it still remains one of my faves.

Story is pretty simplistic, but the characters are all memorable, Lyn was top tier waifu material back in the day, Hector is awesome as well, the music is great, the level design was good and that classic Fire Emblem gameplay just never gets old.
