One fan on the Bioware message boards predicted the ending to Mass Effect 3 long before fans got their hands on the game. More precisely, two years before fans got their hands on the game and warned that it would be the worst possible outcome for the franchise.
A user that goes by the name of Screwoffreg relayed his prediction for Mass Effect 3.
“There are two endings I wouldn’t like for Mass Effect 3. One being a random GOD LIKE force that saves the Galaxy or another being that to defeat the Reapers, everyone has to become a primitivist and destroy the Relays, Citadel, etc. Both would make me pretty unhappy as those endings have been done to death.”
Apparently Bioware needs to pay a little bit more attention to fans like Screwoffreg, who not only predicted one, but two, of the three possible outcomes of Mass Effect 3. For an interesting read, and a spot-on call, you can find the full thread at the Bioware Forums.
