That surely is a looong shot, but there is a big appeal to play again in a world you know. To learn more of it's lore, to see how things turned out, etc.
I'm pretty sure AoD2 is not happening in a near future with all the plans you already have.
Do you have
any thoughts on that account? Do you even want to create a new game in the same setting - expanding it, showing it from a different perspective (I know about the Dungeon Rats but personally I hardly see it this way, I'm talking about propper full-scale rpg, not just combat with a pinch of flavor
)?
It might be different considering the huge consequences of some of the player's actions... But skip a hundred of years and most of it will be some fables and legends - never full, sometimes contradicting each other, full of misunderstandings... As most of the lore avalible in game.
