I have been (re)playing the PC and mobile versions of King of Dragon Pass. I am really falling in love with the concept of the game, and I would like to give it a try at a table with some friends.

I'm looking for a system where:

* Players would be in charge of the tribe/clan/kingdom/whatever as a whole, and need to make decisions and guide it
* Players control/represent single characters that are easy to create/replace as the needs of the tribe change (the Clan Ring aspect)
* While player characters can aid in tasks, most tasks are abstracted away.
* The system has mechanics or even tools for generating interesting or unusual events
* I have no attachment to the medieval fantasy world, so something modern or scifi is acceptable
* While players have characters, the focus is on the group they represent as a whole
* Players make decisions, and maybe assign NPCs or their character to temporary roles, but there is still an element of luck
* Time is experienced linearly by players
* I want the focus to be on the big decisions, and not the minutia of, for example, combat

Microscope hits on a lot of those ideas, but there is no element of luck, and there is non-linear time.
Pathfinder's Kingmaker (and kingdom rules) also cover some of what I'm looking for, but in my experience the focus turns too much to the PCs

What is a good system for play like this?
