The world was like The Matrix? You know, where these powerful creatures had deluded everyone into thinking the world was just a fine and dandy place, but secretly they controlled everything that went on? And there was only one person who could restore true reality and save all of mankind, but that he had to die in the process?
. . . oh, wait. Guess that's not a "what if?" question after all! :)
BTW--been playing "The Matrix" on the ol' GameCube. Got me to thinkin', it did.
