Inconsistencies in the timeline of The Phantom Pain

Several inconsistencies were found in the timeline of the game.


 * Some of the songs featured in the game were not written in 1984. Those songs are a-ha's "Take on Me" which was released in October 1984, Dead or Alive's "You Spin Me Round (Like a Record)" which was released in November 1984, Europe's "The Final Countdown" which was released in 1986, and The Cure's "Friday I'm in Love" which was released in 1992. In addition, many of the songs featured are remastered versions of the originals, which were released sometime after 1984.
 * The Walkman featured in Ground Zeroes and The Phantom Pain is the WM-R55 which in reality was released on July 1, 1985. A Walkman of the same model is given to Chico by Skull Face in the opening cutscene of Ground Zeroes which is set in March 1975.
 * Timeline in the Mission 46 is considered by some users to be inconsistent. Chronologically Ocelot first gets Ishmael out of the car, then he comes back for Ahab and brings him to the ship, then the scene were Ocelot is saying goodbye to Big Boss on a bike occurs. Technically, it's possible for Ocelot to be in all of those scenes, but he would have to leave Ishmael while he's escorting Ahab and later he would have to leave Ahab on the ship to come back for Ishmael.
 * A texture of a patient from Cyprus was datamined, the date on his wrist strap was found to be 04/18/2011. It's not clear if it's a story hint or just a placeholder texture.Date.jpg
