A city/colony building mechanic, with 4X elements built around the multiplayer questing idea. With a focus on having opponents that will actually do stuff of their own.

Essentialy, you settle in some wild teritory, and slowly build up a little town. There was a game that did that called Hinterlands. sadly it did nothing else and as a result wasnt all that great.

Additionally, i would propose having rivals, maybe a local empire or the divine order, activeley trying to invade your territory, build outposts of your own that you can raid. Stuff like that.

Thats the stuff dreams are made from. And thats why it wont happen.



On a secondary note:

The Hall of Echos looking like something out of Kill Six Billion Demons
