VONSSON. IS. MAKING. A. PRE-1991. SCENARIO.
That aside, it has already been agreed that we make different start dates: 1991, sept. 11 2001, specific month and day updated by the release 2002, and 2012.
1991 links us with Vonsson's scenario, the sept. 11 thing will cater to those who want to get those war on terror events without 10 years of AI shenanigans screwing up the world, the 2002 date will make it a real MODERN scenario, and 2012 will make it more realistic by removing nukes legitimately (BTW we came to the agreement long ago that anti-air technology would render bombers, cruise missiles, and ICBM's obsolete in that year).
All four of those scenarios end on the same date, but we will make others that stretch smaller timespans if there is a demand for them.
