The polish that has gone into 0.18 is amazing. I'm loving the new assets and UX, though I fear for the beacons in some ways.
I remembered (too late?) that I needed to enable the research queue at at the beginning so that was annoying throughout - I missed that queue.
Fish are still awesome. Fish+Armour with Shotgun/Submachine -> Fish+Armour with grenades (for spawners and biters) and rockets (for worms) -> Fish+Armour with Destroyer capsules. I have forgotten how to laser turret. And who needs a tank when you have fish?
Have not been disappointed. Factorio is every bit as awesome as it was when I first started playing, so thanks for all the hard work on this!
My base is still only using about 1/3 of my 1.5GW of power, so it's pretty small yet and many things are still in design review, but I'll share a couple early lessons learned from this play-through and associated blueprints in the spoilers below. Thoughts and suggestions appreciated, as always.
