Most hours spent on one game?

MMORPG type, Dota, Dota2, HoN, CSGO, now most hours spent on working hahaha.

I got around 4000 hours in Dota 2 but sadly I stopped playing

Probably about 3k hours on WoW, 8k hours of various versions of Battlefield from 1942 through to the current versions

I used to spend the whole day playing resident evil. Because the damn puzzles was confusing.

I think it's cod black ops 2 haha many hours invested

At the moment I have 2570 hours in Garry's mod

2k hours on a game called APB Reloaded lol

easily Minecraft or gmod dont even know with minecraft and 6.5k on gmod

Definitely minecraft and runescape. In minecraft I am sure I have over 8000 hours played and in runescape probably a little more. Since I have been playing these games for more than 5 years.

Only 60 Hours spend in ETS2
