Most hours spent on one game?

lmao i have spent 4000 on league of legends and 1000 on csgo

LIKE 1K in CSGO, almost 600 in Day Z. Day Z used to be the shit

About 6,000 with CS 1.6, one of the games I played without ending until CS:GO came out

700 hours was spent by me in incredible game Garry's mod.Still one of the best games for me.

I've spent around 2000 hours on Team Fortress 2 alone. I've also spent 2000 hours on Gmod.

This is a tough one. I don't know the actual hours I sinked into harvest moon friends of mineral town. I grew up with a GBA and that's the only game I played till I started highschool.

I have more than 3000 hours in DOTA 2, and I'm still noob

The Sims games. So much time wasted. So many houses built. XD

bf3 500 hours or so its amasing game tha still is pretty fun

Counter Strike Global Offensive, almost 6k hours in game xd
