Games

World of Warcraft, EverQuest, and No man’s Sky

Final Fantasy 6, because I have played through it on SNES, PS1, Rom, then SNES again.... oh, and there's 500 hours in Slay The Spire. Maybe also Civ 3.

Dota 2 around 3500 hours. Rust 1100 hours. Monster Hunter World 400 hours. Binding of Isaac 350 hours.

Civ all games and Apex legends with like 6k or more hours.

Apex is from day 1 launch day.

Maplestory and Warcraft 3 almost certainly hold the first two places from an age gone by, but I don't have numbers for those.

For games that I do have numbers for, Anno 1800, Stardew, and Total War Warhammer (especially if you combine the trilogy).

Sigh... Rust

Stardew Valley, Skyrim, and Halo 3 probably top my list. I dumped like 400 hours into Stardew during Covid lockdowns and a few hundred more after

Persona 5 Royal

150 hrs and I'm almost done with it

For me it has to be either the binding of isaac or noita. It's hard to say since i played tboi on so many devices before i got a PC.

Minecraft

Everquest by far. Then League. Then Diablo 2. I dont think theres any game that comes close to the total unrecorded amount of hours those 3 games have.

Pokemon, either Pokemon Sword or Pokemon Violet, I would have to look at the Switch itself to compare, but last I looked at either one it was around 400-something hours. Shiny hunting can be a surprisingly cozy time-waster, lol.

Top 3:

Escape from Tarkov: 14600h

Elite Dangerous: 3600h

The Division 2: 3200h

Easily Fallout 4 or No Man's Sky

Talisman

Planetside 2, Arma 3, and X4 Foundations.

That's a though one... there are more games in my library that I haven't played than ones I did.

Maybe Fallout or Neverwinter Nights. Or Silent Storm.

Yes, I'm old. And waiting for my retirement to play all of those I haven't tried yet.

Dayz, 3500hrs and still ticking.

Warframe, by a big margin.

R6: Siege at 1800, followed by Terraria at 1100. Terraria is the better game of the two.

It's either the Sims or Animal Crossing.

Craft the world, Valorant and AoE3

Probably Warcraft Rumble.

Dark Age of Camelot. 6000 hours on my main character, and I had more or less ten characters… I’ll never beat that amount of dedication into a game.

Monster Hunter World. I usually stop playing games after I roll the credits, but I have been addicted to min/maxing in that series since Tri.

Sadly League of Legends, probably Skyrim next, Overwatch and Terraria

I also play FGO since the NA server released(7 years ago) but I don't play more than 20min daily

Over time: probably Contra on the NES, Tetris and Bionic Commando on the GameBoy, Operation Wolf and Sinistar in the arcade. DOOM, Duke3d, and XEvil on the PC. CS 1.6 and CS:S in college. The Gears series on the 360.

Then I had a decade or so gaming drought. More recently: Batsugun, Ketsui (Deathtiny and Death Label), Danmaku Unlimited 3, and Battlefield 2042.

And also Satisfactory. I think I kinda like it better than factorio

The Total War series, I have 300+ hours on Shogun 2, Rome 2, Empire, and Warhammer 2 each. Almost 100+ on most others. Probably have 1000+ hours on League of Legends too.

Kerbal space program

MMO wise, it has to be World of Warcraft. Played it nonstop when I was young.

2nd place is Oxygen Not Included.

I have over 1500 cumulative hours invested in No Man's Sky and Minecraft respectively. I am a casual gamer. I started playing Minecraft in 2012 and NMS in 2017.

On and off for over a decade I've played the original Borderlands on xbox360, so definitely that.
