This Alternate History timeline published at Alternate History Dot Com is described by its author User:Max Sinister as "the Mount Everest of AH". It starts with the death of Genghis Khan in 1200 (thus preventing the Mongol conquest of Russia, China and Persia) and goes until the year 1993. History changes a lot compared to our world, although some patterns seem to reappear. The complete timeline (including stories) is over 800 kB long. Inspired By the RPG GURPS Alternate Earths - the scenario "Centrum", to be precise. It has managed to get its own fanfiction work called Samowar in Atlantis.
