Eh. Fire Emblem has never sold a million. I would bump it down into D-tier, at least until Awakening hits the million mark.
Kirby has sold over 2 million as recently as 2008 with Super Star Ultra. I consider him B-tier.
Edit: Also what are you doing, Zelda is A-tier. Not even a question. Doesn't matter that it has only passed 5 mil three times, this is about sales potential and judging by Twilight Princess, Zelda clearly still has the potential to sell well into the 6-8 million range.
