Valve released episode 3, and it was the greatest thing ever, and they ran out of copies in stores, so woolworths started selling the few remaining copies, but they were real expensive, so Crepliakistan bought the last copy, so world war 3, 4, 5 and 7 were all waged for the last copy, then Gabe Newell flew down in his aeroplane of money and used his fairy powers to turn back time and ensure that half life 2 episode 3 would be released later and not up to the astronomical standards that came before.
Oh and Duke Nukem forever was released as a point and click adventure game set on pirate island, it was alright.
