Thank you!

The short but incorrect answer would be somewhere between 300-400 hours, but that’s from the start of playing Satisfactory (as in, my first time playing this game) up to completing the last launch in the space elevator to get the golden mug. It also includes many nights of just leaving the game running. I originally started (with friends) in the flat grasslands and started moving a lot of production into the area you see in the video. A lot of the coal generators and things built on foundations (the stuff that looks neat) was built by friends.
