What game have you spent the most hours playing?

Grand theft auto 5, first in PS3 and now in PC, this game is so good

And for me Minecraft take a huge place in term of hours

I spent most of my free time in Summoner Wars : Sky Arena . It's a free to play , farming based andriod game.

Garry's Mod. I've clocked more than 2,000 hours on it, and counting.

More than 300 h. in Empirion
dont know why sandbox eat so many hours :D

I probably have thousands of hours in Minecraft. I've played since pre-alpha.

Back when I was 14 I used to spend hours playing Habbo Hotel.
What a game that was!

Not easy to answer this, old school games
Half Life (mods included) been playing that for like 14 years.
Then there's some more "modern" games like The Elder Scrolls V: Skyrim about 900 hours.

Well if it's just on one game it's Dota 2 with 968 hours.

If it's combined from a series then it's Monster Hunter. I easily have 3000-4000 hours between all the games. Both are my favorite game series

I have around 1400 hours on counter strike global offensive. But now i just play some rainbow 6 or fortnite.

I got around 500 hours on Garrys Mod, probably most of the time, it's waiting for assets to download.
