Most hours spent on one game?

Is there anyone who play Yugioh Duel Links? I think only a very few people play that game.

Counterstrike Global offensive
Almost at 5K hours and got Global at 1,5K
Still playing it

I sepent 100 hours in star ocean 3... and over 40 hours in pokemon

I have around 3k hours in csgo and another 3k in LoL. Time spent enjoying is not wasted time.

1Kish hours on GMod. Probably spent more on console but eh, can't check that.
I'm lonely

I think I have about 400 hours spent on the last 2K and I have been spending alot of time on its latest release.

956 hours on GTAV 456 on Garry's Mod 248 on Borderlands 1 223 on Skyrim. That's my top 5

Probably tekken 6. Would come back from college and play that shit from 7pm to 5am, go sleep for 2 hours then go college.

I spent about 700 hour on Skyrim back in 2012. I really hope they make a new one in the next few years.
I spend 1800+ hours on DOTA2 , I am fucking loving this game .

I logged 2k+ hours on Halo 3, it was worth every second
