In regards to your first question, I found Dave said this in discord awhile ago.
I definitely want co-op play, yes. How exactly I implement it I’m not sure, probably your sapiens will be able to work on their stuff and vice versa, and they will be less cautious of or hostile towards each other or something.
Pretty sure this means that you will control your own group of Sapiens, and when you start it will be like what was shown here. Then, if you are friendly enough with another player you will be able to assist them and they can assist you so you can work together and possibly form a de-facto conjoined village in this way. Although being able to share sapiens would be pretty cool!
Also there will be private servers, people will probably host public ones too.
Multiplayer is supported, and though I won’t be hosting servers, players will be able to host their own. I’m focusing more on the cooperative side of things, but you’ll be able to play competitive multiplayer too.
As exactly how combat/aggression will work, there isn’t much about it at this stage as far as i’m aware. A few ideas have been tossed around though.

Will there be a combat/war component to the game?
Hi, the short answer is yes, but I’m not sure yet to what extent. I’m not really planning on it being a major focus, for me the more interesting thing is progressing, constructing, building, advancing etc. But conflict also does add an important dimension to the gameplay, so it will definitely be a part of the game too.
