Well then, in that case, I'll add one.Thread is more of a springboard to share awesome credits songs lol. You'll see I haven't actually contested any entry :P
Fire Emblem Echoes: Shadows of Valentia has a rather impressive soundtrack overall. But after a game where the music ranged from epic to powerful with a dash of weird thrown in for the final boss, what could they do for the credits? Not the Fire Emblem theme, this is a Fire Emblem Gaiden remake, it doesn't do that.
So instead, we get this:
A slow ballad sung by a somewhat minor character in the game, of course. Silque singing one of Mila's songs, showing that the divine Earth Mother dragon knew exactly what was going to happen from the start. It's a sad song, but also one of hope.
And after bold epic music like the final map, and various boss themes, it is an unexpected choice to basically have a sad ballad at the end. Unexpected, but not unwelcome.
