Most hours spent on one game?

6-12 hours a day either leveling in mmo's or playing csgo is a typical day

I think the only two games where i dedicated most of my gaming time were:

SA-MP: Started in 2009-2014 spent more than 4k hours in this game as I had a nice server there.

CS:GO Spent over 5k hours in this game, never got bored, earned a lot of friends here and cherished this beautiful time with them together.

Pokemon Red back in '99

I had ALL 150 Pokemon and I swear to god it took me about 2 years.

Personally, the most hours ever spent in a game has been Garry's Mod for me at about 2.4k hours.

Eww... Cant hold up with those numbers, like srsly guys wtf :D Most i played should be minecraft (but not tracked >.<). Steam says highest game is GMOD: 800h

Around 10k hours on minecraft xd i was so fucking addicted

okay I got way more hours then anyone here I was in the minecraft beta get on my level

Probably about 3000 hours on Minecraft, I have 1500 hours on gmod and in Little Big Planet 2 I have probably about 1000.

I think I spent over 1000 hours playing the Total War series. God I loved that stuff back in high school.
