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.

I played Dark Souls for 80 hours before I thought it was crap. Shit graphics (on the Xbox 360), shit difficulty, no story, thought the game was just one big trollface, tempting you with ideas that might pan out, but don't. I kept playing because everybody else thought it was the best game ever, and convinced myself that it was like other RPGs, where if you grinded enough to get the right gear, you could tame the difficulty. It didn't. Difficulty for older areas was better, but new area difficulty was still shit.
