I didn't even know this sale was happening, but it coincides perfectly with me playing Dyson Sphere Program for the first time.
As a 2000 hour Factorio player, I gotta say it feels like I am playing nearly the same exact game but in 3D.
There are some better aspects: DSP's belt placement is far easier on my wrists, liquids are transported on belts so you don't have to worry about the black magic that is fluid dynamics in pipes, vertical building possibilities (literally) add a new dimension to your blueprint designs.
And some worse aspects: no logistics circuit system which means your amount of fine control and ability to create complex systems is pretty much non-existent, NO FRICKIN LAMPS? SHIT GETS DARK HELLOOOOOO?, and fewer mods.
