the Zelda series makes sense based on how he's got these grouped together
6 = Majora's Mask 5 = Ocarina of Time 8 = Wind Waker (or Twilight Princess if you consider Oracles side games) 3 = A Link to the Past 7 = Oracle of Ages/Seasons (or Wind Waker if you consider Oracles side games) 1 = Legend of Zelda 2 = Adventures of Link 4 = Link's Awakening
