What video game have you played the most in your entire life?

I would have to say it would be between Diablo 2 , Elder Scrolls and Fallout series. Definitely Fallout 76 over the past few years I have 4,000 hours. I'm just addicted to building my own camp in a Fallout Universe in an open world and showing it off to other players. I spent a lot of time on Fallout 4 creating cool camps only to wish that they would be visible to other people not just NPCs. LOL how about you guys? Which video game have you spent the most time on in your life?
