Most hours spent on one game?

I have spent about 500 hours in fallout 4, its a very repayable game

During my lad'dom,I played through Final Fantasy VII twice.... win

I once played Fallout 2 and I played it from waking up to going to bet all summer long.

CSGO has got to be the one for me, either that or minecraft from when i was little

I don't even play for that long. Maybe like 50 hours on BO2.

i will say csgo 5000+ and minecraft 2000+ i spent lot of time playing

I currently have 4,742 hours on CS:GO and then on euro truck sim 2 I have 2,383 hours.. YEah I got no life.. ):

Id say Halo 3 is my most played game followed by CSGO at 3000 hours

CS:GO about 1200 hours, Minecraft about 2000 hours

I've spent many hours in World of Warcraft (20k+), even since before the first Korean Open Beta, and in recent years many hours in Warframe (2k).
