I have been a fire emblem fan for over a decade now, and recently started collecting physical copies. I have the switch games and an old Awakening copy. I was looking at Fire Emblem Echoes: Shadows Limited Edition 3DS, since I do not own a 3ds I was thinking about this one. Does anyone know what a fair price for an open box set is? I would use it as my main DS while adding it to my collection.
