I have just under 3,000 hours. I believe i got the game in 2016-17 and i put most of my hours in for the 2-3 years after i bought it. Now life is busy and i average maybe 15 hours a week. The game is great at relieving stress for me though, my job is hard and downright torture sometimes.
Steam its currently sitting on 324.3H. Non Steam release (Hard to believe that was a thing in the early days) it must of been an extra 100H or close.
An Astounding 5,519.6 hours in just 4 years! It may not be the OVER 9000!!! that I've seen posted, but you gotta remember I Got the game December of 2016, may as well round up to 2017. So in 4 years I've logged 5.5k If you do the math. someone getting 9k since 2013(8 years) vs 5.5k in 4 years(since 2017) The 9k is less play time vs the time span I think my average hours per two weeks fluctuates around 50, sometimes 100 hours. My next closest hours in a game on steam... 409.9(lol yeah I know no contest) "Carmageddon Reincarnation" and the OG Carmageddon was my favorite game since 1998 up until like 2 years after getting BeamNG when I realized I could not truly say that anymore and passed the torch to BeamNG. Edit: Yeah, almost forgot there may be a few hundred or so offline hours.
Teardown is pretty awesome too, Ship Breaker is got some interesting destruction also if you never heard of that one. One that I got a while back and never really play. Spend most my time in beamNG.
Ultima Online would be my most ever played, no idea how many but I had a real game addiction then. I guess I am still addicted to games just older in denial
