Most hours spent on one game?

I have an incredible 768hours log in Pokmon Black on my 3DS; for the lasts games i've played, mostly Monster Super League on my phone with a lot of daily play; Breath of the Wild and Megaman X Collection with 30~ and 40+ hours each :D

Arma 3: 1996
CSGO: 697
Rust: 1731
ARK: 3110

I have played Persona 5 for more than 200 hours in just one month and I am on my first new game+

Space engineers: 690 Hrs
Elite Dangerous: 433 Hrs
Skyrim: 135 Hours

And thats just what steam has captured

2K hours on WoW and I feel like a garbage. I should spend the time more with my family

BF4.....I have lost thousands of hours to that game...and damn skippy I dont regret any of it!!!!

Does being stuck playing EVE online count? I had been playing it for about 3 or 4 years and got tired of playing actually.

I've most likely spent 2000 hours on Smash Ultimate, it has to be the game I am most dedicated on currenly

I didnt count for hours but it should be StarCraft or DotA.

The most ive spent on one game is 1400hrs on arma 3
