YMMV / Nintendo Adventure Books

• Game-Breaker: The point system in Koopa Capers where it is possible to finish with more than the maximum if you win.
• Hilarious in Hindsight: A cursed food that causes a Mario character to inhale others and kicks off a "Fantastic Voyage" Plot? Not the last time that idea would be used.
• It's Easy, So It Sucks!: A few of the puzzles are subject to this.
• Nightmare Fuel: It wouldn't be a gamebook series without it.
  • The Crystal Trap:
    • It's loaded with endings in which Zelda (the protagonist this go-around) gives an Oh, Crap! as she awaits a terrible fate (sinking in quicksand or becoming a sitting duck for enemies) for failure to have the correct item.
    • The whole book is one big And I Must Scream moment for Link, who is frozen immobile in a block of crystal at the beginning of the book and will be that way irretrievably if Zelda can't find the Plot Coupons to free him within 24 hours.
  • The Shadow Prince has an ending where you are wrongfully imprisoned and cannot escape as you see Charles run away with the Triforce of Wisdom. Then his mount becomes a giant winged lizard and you realize Ganon has already won, and you can't stop him this time.
  • The Non-Standard Game Over from Pipe Down! if the Mario Bros. don't have enough coins to give to a Clawgrip. The result has the word PINCH! in a gigantic explosion graphic that takes up the entire page.
• That One Level: Koopa Capers, The Crystal Trap and Pipe Down! may be the hardest in the series.
