I have been putting together ways on how Tyria can change according to players actions. Dungeons, dynamic events, and zones are the stage for the living story. We have all, hopefully, done the story missions at least once. Why not evolve it further than 3 paths? Maybe implement a completely different story that grew from the prior. Relationships would be mended, can show the growth of destiny’s edge. Dynamic events and zones go hand in hand for obvious reasons…. For example Orr, now cleansed of Zhaiten, can slowly loose its undead population. Some areas would stay forever “dead” just to keep it there. Dynamic events could change from seizing hold of the land, to defending it and rebuilding it. It can even lead to a whole opening of new mega dungeon portals! what i mean by this is the temples could actually inhabit the gods once again, or at least an avatar of them, and UW and FoW come back!
just a bunch of ideas I have had that i thought could be of use or at least interesting to discuss..
also forgot to mention this..Fractals could be utilized so much in retelling old Tyrias history. Old dungeons can be re done, old dragon fights, all sorts of past content can be shrunk down into fractal form.
