Games

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

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

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.

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

2nd place is Oxygen Not Included.

If we're counting every Pokémon game as a single one, then that. Otherwise, probably Skyrim. I must have like 2000+ hours across all of its versions.

Star Citizen (no joke, I have put more than 2000h in the Alpha...). But because some people may say Star Citizen is not a game (I'm not agree with that statement), the second game I have played the most is warframe (1500h)

I quit a couple years ago for good, but my main account on RuneScape was created in classic as a kid. I had about a year and a half of PLAY time on the account, mind you the vast majority of that was back when you had the hard 5 minute afk timer, so that was at least moderately active play. Then if you add my ironman account I have nearly 1/15th of my whole life logged into RuneScape. I don't regret it, my whole friend group as an adult stem from those friendships I made online during my young teen years. However, as a modern game as much as I have a place for it in my heart, I found I had more of a negative addictive relationship with it. Maybe I always did, but I didn't feel a negative mental effect at a young age.

I have over 1k hours in The Long Dark and 7 days to die. Around 500 in space engineers, darkest dungeon, binding of Isaac, enter the gungeon, grim dawn, and satisfactory. ~300 hours in ToME4 and Caves of qud each. That's just steam stuff though, there are a lot of games that I know are up there that aren't on steam.

I'm sure I have at least similar numbers to 500-1k if not much higher in Diablo 2-3, and I'm sure more than a few thousand in wow though I lost my og account after wotlk because I forgot the details when I quit so I'm really not sure.

Top 3:

Escape from Tarkov: 14600h

Elite Dangerous: 3600h

The Division 2: 3200h

Easily Fallout 4 or No Man's Sky

Talisman

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.

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.

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.

Planetside 2, Arma 3, and X4 Foundations.

Persona 5 Royal

150 hrs and I'm almost done with it

Old-school RuneScape, 12k hours, another 6k hours on rs3 pre-eoc. Over the course of 21 years.

Warframe, by a big margin.

Sigh... Rust

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

Skyrim and Satisfactory.

I would love to know for sure. I've put hundreds of hours into Final Fantasy 8, Final Fantasy X, Morrowind, and probably Halo: Reach too.

It's either the Sims or Animal Crossing.

XCOM: War of the Chosen

Overwatch (gave up on blizzard a couple of years ago though)

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

Apex is from day 1 launch day.

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.

Craft the world, Valorant and AoE3

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

Factorio 5k+ atm

Unless we count pokemon, played that to death when I was younger, would be willing to say I have "young person time" amount of hours in the Gameboy versions.

Elden Ring and StarCraft2

Probably Warcraft Rumble.

I have over 3K hours on rust on PC. If I include all the hours on Xbox when I was younger it would most likely be either destiny 1+2 or Rianbow Six Siege but Im not sure how to find all that info since alot of R6 was on Smurfs

Terraria. I don’t know why but the progression in the game feels so damn addicting. Mods add onto it by alot too

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.
