Flashbacks
<p>Flashbacks are video cut scenes of "what happened last time" but with a few changes put in. Usually small things, that should go unnoticed but affect the character in possibly less than subtle ways, but sometimes the changes are large such as someone they interacted with no longer existing in the scene, or it being a different person.
Every player and npc who had previously crossed that location/object/person/event, would be affected by it.
Everyone is affected by everyone else's actions
The higher up an area that receives the change (capital city vs village farm) the greater affect it has on the world around and other players.</p>
