Not sure if I've tried that (starting new game enaut proposed). However, it took somewhere close to 30 hours to get to the point that playthrough was where I had just started building large unified factory finally having tech and resources for it. That is longer than I've played many games in total, even good ones. I have no interest Right now for early game handmining and manual drafting even basic ingots.
So I will either get to continue that game where I was or or stop playing the game alltogether for a prolonged period of time, and any place I have a chance to review the game the review will not be positive.
