Don't forget about maxing every skill level to 100. Sorry, I've got nothing else to offer.

I did a playthrough were I made at least one of every craftable item and maxed the upgrades out, but I couldn't tell you how long it took me. I would guess around 250-300~ days, but I honestly don't remember. A lot of my nights were spent mining the ore needed. So, I didn't sleep much. Though at the same time, I wasn't rushing either. I spent a lot of time making every one of my satellite bases look and feel decent.

I feel like it would be possible to do something like that in around 200 days or so if it was your main focus. It always helps if RNG is on your side too!
