Dota 2. 7882 hrs

I'd guesstimate upwards of 5000 hours in Minecraft.

I would guesstimate over 12000 hours in world of warcraft

Please send help.

No Man's Sky. I think I'm around 800 hours on that one

Stellaris

Stardew Valley with about 650 hours

Hard to say, I've been on an OpenTTD (since Transport Tycoon), Dwarf Fortress (since .31), Minecraft (since Tekkit) and Factorio (since .11) loop for several decades now, with 1000s of hours in each. I tend to play one at a time, currently doing Enigmatica 6 Expert.

Borderlands 2

How on Earth does one spend 557 hours on Final Fantasy VI? I've finished it at least a half-dozen times over the years since it came out, and I doubt I've spent that much time with it. And at least one of those sessions I got everyone to max level and taught them every spell in the game. I suppose I have not taught Gau all the possible Rages, but doing that sounds insufferable.

Edit: Are replies broken? This was a reply to a comment, but it showed up as a separate comment.

7 Days to Die. It's an incredibly underrated game. I'd describe it as Minecraft, but for adults.

They've reset mine twice before many years ago. I'm sure Minecraft is my top overall. In steam it says Metal Gear Solid 5 is my top but I would leave it running sometimes for the research to finish. Second is Garry's Mod. I played that A LOT when I was younger.

Where are you people getting all this time from?!

Team Fortress 2 with 2075 hours and that's on an account I made 4 years ago. My old account had 3000+ hours.

Crudader Kings 2 at 1400 hours and Total War Warhammer II and I at 800 hours

Stellaris almost 600 hours and Cities Skylines, around 400 h. Damn!

Minecraft. 2.5 kilo hours

Diablo 2. Heroes of Might & Magic 3 coming next.

I might have more hours @ World of Warcraft, but that's outright drug and wasn't played for most of time voluntarily.

Dunno if counts as a game really.. But about 4k hrs of VRChat - love the place and the friends I made there!

Final Fantasy XI. On and off over the list twenty years I probably have about 3 to 4 years worth of game time. 2 of those years were put in between 04 to 07.

hotline Miami, katana zero, ultra kill.

Diablo 2 from launch, I won't even guess the hours because it's over 10k easy and that's just not good. Path of Exile says 4k+ hours as well. I'm an old fart though.

Microsoft flight simulator thanks to slow internet and 200gb updates every time I play.

That would be Elden Ring. Spent 200+ hours on that game (might sound like rookie numbers but that was my first open world game, was just a casual gamer before that).

This is a low ball but I easily have 3000+ hours in FFXIV and Old School Runescape (not combined)

Factorio - 364h on steam and god only know how many outside Planetary Annihilation: Titans - 332h BeatSaber - 230h

But compared to other gamers ...

Looking at 600+ hours in Rimworld, and probably even more in Dwarf Fortress but 200+ since the Steam release, it wasn't tracked before.

If we count map editors then most likely C&C: Generals: Zero Hour or ARMA 3.

If we don't could editors then probably Halo 3 or MW2, maybe Stellaris.

Satisfactory. I'm well past 1,500 hours.

The factory must grow

Minecraft easily. The game doesn't record hours but if I were to guess it would be at least 10k hours.

Second most played game has to be Diablo 2. In Diablo 3; I have 350 hours on one character, 200 hours on another, 125 on another and various temp character that I play during seasons and delete probably another 400 hours there. With all that being said about Diablo 3. I've definitely put more hours into Diablo 2. I would guess at least 3000 hours for Diablo 2

Game with the most hours played on Steam is Town of Salem at 750 hours and then Grim Dawn at 360 hours.

AI (Alien Isolation)

Satisfactory with 752 hours. No mods, either. Most recently is Project Zomboid with ~123 hours.

On steam it's dota 2 with about 3k hours but really my most played game is the old f2p Combat Arms. I nearly exclusively played that game after school to bed for like 4 years, I probably had over 6000 hours logged. Still talk with the friends I made there a decade later.

I've got nearly 800 hours into Cyberpunk2077.
It'll probably be my goto game until its sequel comes put in a decade or so.

I must say, there are a surprising amount of factorio players on this threat, glad to see that!

Definitely factorio, but I can't tell you how many hours. I started playing on steam, but then downloaded it from factorio.com and had multiple installs so I could play different mod packs. Steam says 1100 hours, but it's got to be 3 or 4 times that, total. I've played multiple saves that took several hundred hours
