Factorio's FFF blog posts have always been amazing.
From deep dives into development, their automated testing systems, terrain generation, and hyper-fixation (in a good way) on optimisation and QoL, through to more meme-ish and lighthearted things.
Im sure there is a great story of an indie developer making the best/funnest production optimisation games out there, all in the FFF blog.

Im so glad they are writing them again, even tho im not playing it at the moment
