I'm so very addicted.

Warframe - 2000 hours in one year

Blood Bowl 2 : 306 Hours

Defense Grid. 41 hours. Followed very closely by Dark Souls, Borderlands, Deus Ex: HR. Chump change compared to all of you. Most of my longer played games are not through Steam like StarCraft.

DigiFish Aqua Real 2

Rocket league 2156 hrs

1320 hours in Warframe for Steam, and 2190 hours on Guild Wars 2 (non-Steam)

Football Manager 2015
124.7 hrs last two weeks / 3,932 hrs on record

slay the spire- 484 hrs

Mass Effect 3 on Origin - 401h

Stopped to play it few months back due to lack of time.

X3 - too many hours to admit right here :P - now replaying as X3AP as I refunded X4 with sadness :(

1.7K hours in CS:GO, big mistake, but back then it was different. Second is R6 Siege at 470 hours. Most overall playtime, GTA SA back in the days, I dont even want to guess how many hours, but a lot.

On Steam it's Rocket League, 2,461 hours (though a good chunk of it was leaving it on overnight). I've probably spent a lot more time on Halo Online, don't know the hours but I've played 2,780 matches that last 5-15 min since the .6 update on 4/20 last year, and have played about the same amount since mid 2016 :P

That may be changing soon though...I'm heckin hyped

Binding of Isaac - about 400 hours

ARK: Survival Evolved at about tree fiddy hours

Wow, I'm such a gaming lightweight. Or at least, I don't have the patience to grind away at a single game for hours.
My record is Fallout 4, with 279 hours.
Coming in a close second is Titan Quest: Anniversary Edition, with 248 hours.
Then it's TES V: Skyrim, with 215.
Everything else is under 200, and I've only got 8 games with more than 100 hours.

Number 1 overall is Warlock: Master of the Arcane (like a pretty Civ II!) with 285 hours

My most recent obsession is the to-be-release-on-Easter Faerie Solitaire Harvest - I currently have 75 hours in it. SO GOOD, and the game is not even finished yet!

Train Simulator - 270 hrs.

Warframe with 500+ hours.
I joined it as a Disciple founder just after closed beta, and stopped playing after they added players got their own ship & pets. Good times!

Survarium -690hrs)

On Steam sadly it's Metal Gear Solid V: The Phantom Pain - around 80 hours, but I played 500 hours of Battlefield 3.

Steam
Warframe 3,276 hrs on record
PAYDAY 2 2,486 hrs on record

Origin
Mass Effect 3 738 hrs on record (far more cause Origins doesn't count the time I spent on it as "borrowed" when it was released)
Battefield 4 544 hrs on record

Uplay too bad didn't have time record for old games cause I was addicted to Splinter Cell Conviction and Blacklist
Ghost Recon Wildlands 541hrs (288hrs Solo + 253hrs Coop)

the original defiance, even after my timer somehow got reset, total its 800+
