My top 3:

1. RimWorld

2. Skyrim

3. No Man’s Sky

If MMOs count, EVE Online at well over 12,000 hours over the last 20 years.

If not, nethack has probably consumed close to 1000 hours of my life.

I’ve been playing & modding Neverwinter Nights since 2005.

Almost certainly World of Warcraft. I don’t think I even liked it for most of the time I spent playing it. I’ve been annoyed about the overall direction since basically Cataclysm, and IMO Burning Crusade laid the foundations for most of my major complaints, although I didn’t realize it at the time. I have decided that I’m opposed to the “expansions add a new tier of everything that invalidates old content” model of expanding games. If creating diverse content that is still enjoyable at level 60 is too hard, then maybe games just don’t need to be expanded indefinitely past their original level caps.

Guild Wars & Guild Wars 2

Steam says Borderlands 2, but I must’ve accidently left it running or somethingbecause I definitely haven’t played it that much.

Next would be Sunless Seas and Frostpunk at around 200 hours which sounds about right.

Deep rock galactic. 1500 hours. 😬

Rock and stone!

Im not sure about total hours…

But several thousand in WoW. Back during release and for at least 5 years i played like 8 hours per day on avg. I would guess.

I would estimate 10000 - 12000 hours. Maybe a bit more.

I dont play it anymore though.

The game i have most time played on, on steam, would be Gfim Dawn. That game is amazing.

According to Steam I’ve spent 5121 hours on Fallout 4.

That would be:

Dota 2

Warframe

Path of Exile

Skyrim

Mass Effect 3

Dragon Age: Origins

Apex Legends

seems like the only game I ever play these days is the Halo Master Chief Collection… just play through all 6 campaigns then start over again

I like games I can just pause and walk away from for a bit. Or just play while watching videos. So the hour counts are never really accurate. But I can safely assume in the past few years its Rimworld. It’s my game I can play while doing other stuff. But if I crank up the speed it’s engaging enough to focus on if I want to.

Lifetime totals it may be Minecraft though, I usually go back to it every few years. The urge comes and goes.

Garry’s mod by a wide margin. I’ve been playing for more than 10 years and accrued around 2000 hrs

Warframe, just hit over 2k hours. I have a plethora of other games that are over 300 hours each like Rimworld, Fallout NV, etc

Absolutely WoW, but Path of Exile behind that with 1900 hours…
