So I'm a tad confused. Does this RP take place on the same planet as ours, and this is simply player-created alt-history. Or is this a 'pseudo-earth' with alternate continents, etc and ALL history is left up to players? To make my question a bit more simple, if this takes place in our world, what point would the 'time divergence' happen? What events played out differently to ALLOW such major divergences?
