What is Nintendoor?
1.
A Nintendoor is a term referring to an impassibly hard segment in a video game. The term comes from the idea that if game makers create obstacles hard enough they will make money from you buying a guide to get through the "door."
It originated from playing Nintendo games, but is now a general term for a difficult game spot.
"This game has so many Nintendoors I had to buy the guide."
