JaqFrost: "In
Unwritten the player creates and guides a nomadic clan on a one-way journey across a dangerous wilderness. It is a turn based strategy game with maps, story elements, units, abilities, and enemies that are all randomly generated. Along the way decisions (and death) are permanent, and each play session is unique."
It seems the lead is one of the original team members for Dishonored and they're planning to release their development tools to the community right from the start.
That sounds really interesting, although it seems more like King of Dragon Pass with added roguelike elements than Civilization.
And while I love KoDP, I typically dislike roguelikes. I'll wait for more information, I guess.
