That's actually not an easy start. I don't know how comfortable you are on immortal, but I wouldn't make my life difficult like that.Should I do settler first even without imperialistic? Here I rolled a map with one flood plain and a plains cow but I'm on a PH. Elizabeth, pangea, immortal. I think if I go worker first I would farm the flood plain, build a mine and chop, which is not that attractive.
