Well they keep updating it, so it may not have been there, unless you made a chest sphere and didn't label the chests.

Per my steam library:
Factorio: 3,375.4 hours
Dyson Sphere Program: 2,505.9 h
Stellaris: 2,236.6 h
Terraria 2,629.9h
Skyrim: 1,239.5 h
Dungeon Defenders only has 600 hours on Steam, but I'm well over 2000 hours between Steam and PS3/4
I've also got a few thousand hours in Just Cause 2&3, as well as several Gran Turismo games and Forza Motorsport games. Morrowind probably has 2-3000 hours, oh and I'm not allowed near Sid Meier's Alpha Centauri anymore.
Secret of Mana and Chrono Trigger are probably up there as well since I'll replay them every decade or so.
Small Soldiers also taught us how to turn an electric pole transformer into an improvised EMP device. That turns the dogs off.
Second Life.
Then you zoom further out to find that the Blokkats have moved into the star system next door, and are eyeing Sol hungrily.
Shit, I cross the road to overtake because I'm a smoker and don't want to inconvenience non-smokers with my addiction. Never even crossed my mind that may make people feel safer.
Lexington, KY has a ton of horse hitching posts/ bike rack posts. That may be because they maintain a fairly decent mounted police division.
Each new planet is basically an overhaul mod. They did a great job incorporating the best parts of Space Exploration, Krastorio, Seablock, and a couple mods that either they made up entirely, or I didn't know the names of.
Also the overhauls to the fluid handling and circuit networks make everything so much easier. I'm actually learning how to use circuits and trains, and I only have about 3000 hours of gameplay in vanilla.
My best advice is to rush bots, and leave even more space in-between your modular builds. Holy crap do I have some spaghetti because of squeezing things into my bus.
Factorio Space age is 4 expansions in one package. We definitely still buy proper expansions.
Sorry to hear about your MPD

I'm 44 years old, and have been gaming practically since I was born. My parents played D&D, and video games with us kids.
Also a lot of those totals are artificially inflated because I can leave the game running to finish a long task, especially Factorio and DSP
