I can just imagine some masked, Mayan death-god standing before a closed gate, checking his watch, comparing it to that damned, prophetic calender. Suddenly he'll shout, "Open the gate!" and the door will fling open, spurred on by the power of his voice.
And lo! Hordes of dickless cav will pour forth, and kill everyone on earth while they're sleeping. You know, because cav only kills AFK's.
Peering through the gate, one would see, in his last moments, a Field by The River. The source of the apocalypse would look suspiciously like cRPG.
And the Mayan god would remove his mask, and there's chadz. Sneaky guy. It was all a lie...
