Would it be an idea to send out a massed mail to all players who left the game, reminding hem and trying to entice them to return?
Like a short overview of what's been happening on the continents as to spark their interest?
Perhaps people that left before now have time again and all they need is a little reminder that this game is still around, alive and kicking.
I know that I would likely be irritated to receive an email from a game I quit. If something like this was implemented, great care should be taken...
