Whats the deal with the three-day time limit?
Majora’s Mask features an internal clock that counts down for 72 hours. At the conclusion of 72 hours, the moon will crash into Termina. One game hour equals about one minute of real time, so to play through the whole three-day cycle it takes a bit longer than a real hour. Link travels back in time at the conclusion of the 72-hour period and lives the same three days over and over until he stops the moon.
