Most hours spent on one game?

Well. I have around 2k hours in minecraft, 2k in Rainbow Six Siege, 3k in Gmod, 2k in CSGO. I also have seen a dude with 25k+ hours in Gmod for some reason.

Umm hands down wold be Fallout New Vegas. I believe I have over 4k hours on that game total. Literally play that game every day since it was released.

10k on Garry's mod, pretty sad but whatever .

I have easily 10s of thousands of hours spent on world of warcraft lol it's honestly kind of sad

would have to be cs:go 378hours untill i got banned for so called hacking lol

The most ive spent on one game is counter strike i spent 2000hours

American Truck Simulator - 8 hours on one the winter breaks weekend.

According to steam, Garry's mod with 2.3k hours, GTA V taking second with only 514 hours.

But off of steam, probably Minecraft has taken over my Garry's mod time x3. I'm unsure though..

Dota 2 at12k hours. Started playing from beta and everyday since atleast 10 games daily.
