As a series, Fire Emblem has had two standout features compared to other tactical RPGs. First, characters can build relationships with their allies, and in more recent entries, even become romantically involved. Fire Emblem: Fortune's Weave doesn't focus on the seduction side at all, preferring to show the camaraderie between teammates. The second feature, one that's been there since the first NES game, is that characters can permanently perish in combat.
