Longest is 2,700 for a bad review. Oxygen Not Included. The hours come from a combination of things.
I bought it on a whim the first week of early access so years of on and off playing. Mid game gets super slow and with a stable base there is little danger. So que up some dig, sweep, or build orders and go to bed. 20 minutes of play for 20 hours of run time.
Then the game starts to have problems with performance so sort the junk and fill the world with plastic to simplify calculations.
Then there is the runtime I used running a mod that generated a world checked it's stats and sent the info to a map database.
At work a mix of red hat, fedora, centos, and red hawk. At home mint debian spin. It just works and games run great. I don't have time to deal with the red hat crap if i'm not getting paid.
