You spend a small amount of time each day meticulously crafting the factory/garden to unwind. The time it takes isn't a problem. The goal isn't to 'win'.
I've played Factorio (and Satisfactory, and DSP) and I understand that you can just do a bit here and a bit there but still. And I've spent 1,500 hours in some games (with a couple of hours a night, most - but not all - nights) too. Even so, it's intimidating to start such an endeavour.
