The pinnacle of Fire Emblem. Amazing story and characters. Even side characters like Jill and Harr have great arcs. Every part of this game feels fully realized and fleshed out. Only flaw is that the battles are slow, but it's really not that bad, as I've beaten this on consoles several times, and 99% of people who play this in 2020 are gonna be playing on Dolphin with access to a speed-up key.
This is the bar in which I rate other Fire Emblem games, and honestly, games in general.
