The tracked playtime is incomplete since the feature was added years after Steam launched. It's missing all of the data from 2003 to March of 2009. It also doesn't show offline playtime, which changes things quite a bit. CS 1.6 and Total War: Medieval 2 would top the charts by a long shot and TF2 would have plenty more too. Adding MMO's and games on other launchers would obviously also change things by quite a bit.

As for the tracked time on Steam:

Warhammer 40,000: Darktide - 585,5 hours
Tom Clancy's Rainbow Six Siege - 500,6 hours
Mount & Blade II: Bannerlord - 337,1 hours
Total War: Warhammer II - 306,4 hours
Total War: Warhammer - 305,3 hours
Team Fortress 2 - 293,8 hours
Deep Rock Galactic: Survivor - 289,3 hours
Total War: Empire - 246,9 hours
Palworld - 235,7 hours
Total War: Shogun 2 - 217,5 hours
Blood Bowl II - 179,6 hours
Total War: Rome II - 174,6 hours
Warhammer 40,000: Inquisitor - Martyr - 171,5 hours
Assassin's Creed Odyssey - 170,2 hours
Helldivers II - 140,7 hours
Baldur's Gate 3 - 128 hours
Pillars of Eternity - 122,1 hours
Cyberpunk 2077 - 121,8 hours
XCOM: Enemy Unknown - 120,3 hours
Mass Effect: Andromeda 120,3 hours

I've got several games in the 110-120 hours range, some of which I'm actively playing. Some on the list I'll be picking up later again to go through some new content that I just haven't had the time for yet.

Seams we have the same social life :lunar2019grinningpig:

pretty much work, eat, game, sleep. rinse, repeat. But if i have to actually add, some more hours to three games which i had illegal copies of years ago before i bought it, then it would be good couple hundred hours extra

You can find the number of hours I’ve spent on my top 20 games if you know where to look, mr dataminer

Im ashamed of it don’t look
