Version 3.5 indeed was better, almost everything changed for the worse in 4.0. Why there aren't 1x1 block drills along the 2x2 ones? 2K material cap? Wtf? No explanation for anything. You can't see what you'll be getting in the future because everything is hidden until you unlock it. I hope they change their minds and make the game more like 3.5 back again and improve upon that.
