Most hours spent on one game?

Destiny/Destiny 2 which is probably around 800+ hours, unfortunately I don't play anymore since my friends switched to PC

Between my main account and all of my smurfs on Overwatch, about 3k-4k hours.

Has to be World of Warcraft for me...I eventually stopped looking at my /played lol

Football Manager 2019...2.5k Hours...but that's with Steam counting. Realistically, probably 200 of that is played hours. I'd say it would be CS Source, with probably around 4k hours.

I've played Morrowind at least a dozen times. I've been playing and replaying it since I was a kid!

This is surprisingly difficult for me.

I have around 3,200+ hours in Warframe. However I may say the most time I spent in a game is honestly Minecraft. I've been playing it since late alpha. Only originally got my first account around 1.2.3

I may very well have over 30k+ hours in Minecraft.

diablo 2 easily, been playing that on and off for damn near 20 years now, probably have at least 8000 hours.

Counter Strike Source has easily absorbed over 4000 hours of my life. I will never get those back :(

Yeah, yeah CS, Dota 2 and all and all. How about 500 hours in Boobs Saga. This. Is. Real. Power. // Not my achievement unfortuantely //

Probably have over 3500 hours in csgo across all my alts
