Okay so the settler really interests me its nice to see something like this in a game its really unique. But from i've seen it's still really foggy. i understand they can help upgrade cities and such, to build taxis and other things but what i want to know is to what extent? and if they can just build camps where ever? Also whether or not they will be useful come a year or two after release where everything is allready built unless what has been made slowly fades away or becomes destroyed.
