I just want to say that I have passed 1300 hours total and 600 on SE. I didn't finish SE before the dlc came out though, and got really burned out in trying to :(.

Factorio is my favorite game ever and as of today, I have 1203.1 hours logged. I am currently playing an overhaul mod called Space Exploration (SE), and have been playing it for (exactly) 500 hours.
