2012, the first guess at the end of the world. Many people predicted that the world would end. The world did not end, but it was replaced with the Gaming Depression. The failure of many games would occur and the industry would not see a comeback until the 2070s.
2042, the next guess, another guess done scientifically by Mayan descendants (still not correct).
2062, another one of Nostradamus's descendants made a guess.
2150, everyone was so scared, but the prediction was completely wrong.
