It's not particularly earth-shattering or anything, but while consulting my copy of GURPS Ogre in preparation for the release of the game later this year I noted in the book's timeline that this year (2012) is supposed to be the one where the USA runs out of oil.
Which is, of course, not even remotely true. But it's based on assessments that a lot of people took seriously ten to thirty years ago - and, to be fair, those people were generally acting in good faith when they received the information, even if the people that disseminated it may not have been - so expect a rash of curiously-dated gaming and SF material to intrude on one's consciousness. So it goes.
