Team Fortress 2

Steam says my top 3, in order, are ARMA3 (though more than half of that has to be with the game minimized as I work on scripts for mods), Team Fortress 2, and Rocket League. All have over 2000 hours, Arma 3 has slightly over 3k.

However, from 1997 to 2007 (literally haven't played it since The Orange Box released), I was playing Ultima Online for at least 8 hours a day, every day. So if that kept track of my play time, it would likely be numero uno. Diablo 2 and EverQuest would be right behind it.

Hard to say, but I would think Minecraft (over the last decade) then Factorio. If we’re factoring in games from when I was younger then it’s certainly COD followed by Halo then Gran Turismo.

Oblivion, Skyrim, Every Fallout (yes even 1 and 2, but especially New Vegas) borderlands 2, Diablo 2 & 3, Stardew Valley, and there were a few years of CoD, and a WoW phase.

Oh. And ten years worth of Hearthstone.

Kerbal Space program (1800.8) DCS world (1172.2) Witcher 3 (1131.5) Sims 4 (838.2) Stardew Valley (579.3)

I just wish ksp2 wasn’t a massive flop and I eagerly await KSA.

World of Warcraft - over 11k hrs

Guild Wars 2 - over 5k hrs

Warframe - 2200 hrs

Minecraft - who knows... a lot

League of legends, Counter Strike and Warcraft 3 custom maps are waaaay up there.

Factorio is catching up though

Around 2.6k hours in CSGO. Quit playing CS2 shortly after release :(

Timberborn. 4,677 hours. I enjoy my beavers.

Probably League of Legends, I don‘t know how to check how many and don‘t really care, but I‘d be surprised if I hadn‘t spent more than in Rocket League which clocks in at 1100 hours. I don‘t play much of either anymore though. Counterstrike 1.6 is at 400 hours but that‘s gotta be a lie and way more as well lol

Europa Universalis 4, and it's not really a close margin. 1445 hr mark is when you've finally completed the tutorial and can start the real game.

Fallout 4 and Skyrim

SteamDB says Rimworld, but I'm almost certain it's actually Fallout: NV, as the Nexus launcher at one point bypassed Steam and so those hours aren't represented. I have about 1100 hours in Rimworld, but probably closer to 3000 in Fallouts 3 and NV.

Lol I somehow completely forgot about Guild Wars 2. Pretty sure my age in that game is over 2 years of active playtime.

Overall? Probably Unreal Tournament (1999). That was when I was at the peak of my gaming time and I would play for hours most weeks and played that basically for a solid decade.

In the modern era? Warframe which Steam says I have over 700 hours in.

Final Fantasy XI and it's not even close.

I have 3,400 hours in Space Engineers.

About 1,500 hours in FFXIV, 1,400 hours in DayZ, and 1,300 hours in 7 Days To Die.

Then 900 hours in Empyrion Galactic Survival, 500 hours in Baldurs Gate 3, and 300 hours in Fallout 4.

The rest are well below 200.

2000 hours in Garry's Mod, 1300 in TF2. Third place is way behind, Hollow Knight at 180.

TF2, Diablo II, and Ragnarok Online. 1k-2k+ hours each.

KSP

KSP. I colonized almost the entire system on chemical rockets alone with bases and ISRU fuel depots orbiting the smaller moons (I'd have to go to each base, do some mining, and refill the orbiting tanker station before every long mission so it's ready when I got there). I'm not at my PC but last I checked it was a couple thousand hours.

Skyrim over 2000 hours easily, 400 some into Assassins Creed Odyssey and Ghost Recon Wildlands; I have no idea how many I put into Vindictus, which is an MMORPG I played for more than a decade. For phone games I’ve probably put the most time into the Kingdom Rush series, best TD out there.

Rocket League, by far. 1500 hours or so.

Final Fantasy XI. Something like 400-500 days, so roughly 10k hours. Though I haven't seriously played since 2011.

WoW, Grim Dawn, Don't Starve (Together), Stardew Valley, Terraria, Skyrim, Borderlands

No hard numbers here, but probably Medieval 2: Total War.

Every few months I get the urge to play and log more hours doing a few campaigns.

Probably 2048 which is just a fidgeting toy for me.

I'm not sure if it's wow or League.

I played League for 10 years but in my adult phase, while wow was mostly while studying so a lot more hours to burn.

Team Fortress 2 easily. Been playing since 2008. It scratches an itch that no other game can scratch. Ironically though, my second favorite fps game is also TF2 (Titan fall 2)

My most played game is hands down: Borderlands 2.
995h in it!

Civilisation, the original one. Got it in the 90s, and none of my computers was without it. Even now I sometimes launch it for a guick, half-day game.

I'm sure other Microprose games from that era, in particular UFO: Enemy Unknown, are on my top 10 most played games.

From modern games, I probably spent the most time playing Civ4 and Heroes of Might and Magic 3.

The X3 games (Reunion/Terran Conflict/Albion Prelude) would be one game with DLC today, combined they're my only 1000hr+ game. X4 is one game with DLC and is well on it's way to that record.

I'm approaching a thousand hours in Elite Dangerous. Quoting myself from a week or two ago:

It’s different to most other games, by not being goal-oriented except for the goals you set for yourself. No main quest line dictating progress. No mandatory tasks. No win condition. Instead, it drops you into a simulation of our entire galaxy roughly 1300 years in the future, where humanity has mastered hyperspace travel and spread through hundreds of star systems.

(To give an idea of the simulation’s scope: Around 85 million systems have been recorded by players so far, and those are a vanishingly small fraction of what’s out there. Space is big.)

I like that it offers a variety of activities to fit whatever mood I might be in on a given day. I can hunt pirates, mine asteroids, engage in a bit of piracy myself, find and collect bio samples, infiltrate rival settlements, venture into vast unexplored areas of space, discover Earth-like worlds that nobody has ever encountered before, defend humanity against hostile forces, photograph beautiful stellar phenomena, rescue stranded survivors, customize and finely tune my ship to perform beyond its original specs, team up with friends, pledge to a political power and expand their influence, or chill out as a space trucker and haul cargo to earn enough money for my next upgrade. It can occupy all my attention, or just be relaxing entertainment while I listen to music or an audiobook.

It’s an MMO in the sense of having a large game world (galaxy) shared by all players in real time, but PvP is optional. One mode exposes you to other players, while another limits you to NPC encounters. You can switch between them at will.

One warning: A space ship has more than a few controls to learn, and they’re better suited to a game controller or HOTAS than a keyboard and mouse. I use button combinations for almost everything beyond basic flight controls, since there aren’t enough buttons on a controller for everything.

I have a lot of hours of Morrowind and Doom 1&2, as well as Warcraft 2 and Ultima Online, but I dunno the hour count

According to Steam the top 3 are:

1. Oxygen not included
2. Civilization 5
3. Factorio

But that of course does not include the games not running from Steam and pre-Steam games. So World of Warcraft is somewhere in there too. And the final Top 1 must be Transport Tycoon Deluxe (even if you don't include OpenTTD).

World of Warcraft is the absolute winner in my case. I have no idea on actual numbers, given 99% of my time was in private servers, with a very brief stint on official. Only one of those private servers is still around, with my character from Warlords of Draenor times still there.

Outside that, probably Skyrim (many hours playing pirate versions, modding it with more lethal combat, more lore-friendly armors and "actual" civil war, among other things). I wonder how many hours I've spent on Dwarf Fortress, as I've only played the freeware version, starting with 0.34, before trees had height.

Stardew Valley and Core Keeper ;)

7 Days to die. 1600 hrs on steam Call of Duty. 1200 hrs on steam

The Binding of Isaac

Braben & Bells "Elite". The original one on the C64.

Probably counterstrike back in the day, possibly battlefield 2 including the Project Reality mod. That was back when gametime wasn't really tracked and I had a lot more spare time Possibly WoW, but I only played for a couple of years or less and for a few hours a day at most.

Currently my highest is Forza Horison 5 with like 1200 hours. Have a few others with 500+ hours although a few are inflated at least 100+ hours because the game locked up on closing and counted as played for several days multiple times.

The most that I have proof of is Europa Universalis IV at a little over 1k hours, but I wouldn't be surprised if my time on Guitar Hero 3 in high school surpassed that by quite a bit. I played a lot of Guitar Hero in high school...

Arma 3

Probably still World of Warcraft. When I quite around 2010, I had close to 700 days /played time on my main, and another 400 days between various alts.
