YMMV / Colossal Cave

• Adaptation Displacement: Nearly everyone who has ever played this game played a port.
• Anti-Climax Boss:
  >KILL DRAGON
  WITH WHAT? YOUR BARE HANDS?
  >YES
  CONGRATULATIONS! YOU HAVE JUST VANQUISHED A DRAGON WITH YOUR BARE HANDS! (UNBELIEVABLE, ISN'T IT?)
• Memetic Mutation: "Xyzzy", a magic word used to teleport to and from a certain room early in the cave. It has become a meme in Interactive Fiction circles, to the point that developers tend to program responses to it in their games.
