Despite Mario and Zelda always taking the limelight, Metroid is one of Nintendo’s most influential franchises. Super Metroid’s design helped define generations of games and create the Metroidvania genre, and Metroid Prime managed to be just as innovative decades later by brilliantly fusing Metroid's meticulous exploration with first-person shooters.
