Because it's so closely tied to real-world events, the Fallout timeline isn't one that's hard to envision like fantasy games where everything is invented. The events of the franchise do fling players into the future, but the games are largely tied to a 200-300-year period in the future. Plus, with nuclear fallout, it's not like there's much in the way of world events. Most of the Fallout world is unknown to players as only a handful of locations, all within North America, have appeared in the franchise over the years. Despite this, the biggest quandary for the Fallout timeline isn't necessarily how everything unfolded, but why it currently ends in 2910.
