First order, straight to Spectacle Island to set up some Water Purifiers to bankroll me (I buy all my stuff).
Lvl 15 start Automatron, complete it as soon as I'm able, just have to see about that I guess. Gonna concentrate on Robotics, Science, Gun Nut, Armourer, blacksmith - the robot building perks.
Gonna wait until I'm comfortable with my robot building ability and cash-flow until I rescue Preston and the mob.
Then I'm gonna start on settlements BUT I'm not gonna do much building or recruiting in them. I intend to man them almost exclusively with robots, the only exception being for traders and only because robots won't be traders. So there'll only be a few beds and some water, some food and .... that's about it. Will even scrounge on food and water maybe growing everything on Spectacle and just using provisioners (robots of course).
Not gonna worry about defence, leave that to the robots, they get attacked often - GOOD! The few humans there whinge about defence - then let them whinge!
Also on this playthrough gonna dumb down my character to the point of not taking perks above what I deem absolutely necessary. I don't want to be invincible, I want to be squishable and rely on cunning over muscle.
All I want is my fibre armoured suit & hat, sunglasses and the Deliverer, a nice silenced .50 sniper and the railway gun for the heavier enemies.
And settlements chock full of robots - they don't whinge!
