The game in my Steam library with the most hours played is.....PAYDAY 2.
But I didn't actually play a thousand hours of it. In the late 2010s, the heat in my condo barely worked and our self-managed association refused to acknowledge it because "nobody else [was] having problems with their heat." I had all the windows plasticed up with heavy blankets literally nailed to the wall. I had to abandon the living room and bedroom entirely. I emptied the smallest room (12x10) and moved my mattress and desk in there...In addition to the playpen for my two rabbits that took up the rest of the free space.
You might be wondering what that has to do with PAYDAY 2. Well....the game revved up my video card to max on the main menu so my PC became a supplementary heat source at night...
Good times. Thanks, PAYDAY devs!
ETA: In the spring, the guy who handled yardwork noticed the flowerbed was kind of sinking on one side of the building. That's when they discovered a leak in the radiator line...small enough that 11 units didn't notice but big enough for the water pressure to not reach the farthest unit from the boiler....the unit I owned...
Great game, it and the original Pixel Dungeon were my most played phone games for years.
Another high quality mobile experience I can't recommend enough is Slice & Dice. Gameplay is quite different from Pixel Dungeon, but it's basically replaced all other phone games for me. Been playing it almost continuously now for the past 3 years.
When I was a teen I played WoW from vanilla through Cata... Had over a full year of in game /played time on just my main.
...and I made a lot of alts.
100% full-blown addicted.
Blizzard is actually the one example of enshittification that I can actually be thankful for - I didn't really ever quit; they just stopped supplying my drug of choice. They definitely had the power to keep me enthralled, but instead shifted to a younger and younger target audience as I was ofc aging the opposite direction.
The Kung-Fu-Panda xpac trailer was finally my cue to accept that my dealer wasn't going to provide that fix anymore.
Then I started making healthy life decisions discovered Ark >_<
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.
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.
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.
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.
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.
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.
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.
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...
I think something like 5k hours into Warframe,
15 years into WoW (at least 2 of my characters have 1+ year of playtime--so 17k hours just on those 2; and I max-leveled every class of character up until Battle for Azeroth)
and so far, 2 years into ARK. Just over 3.5k hours of playtime between ASE and ASA.
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.
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).
I have few hundred hours in Minecraft.
And probably something like 180h in Witcher 3 GOTY.
Recently I 100% Yakuza 5 with 120h on the counter, and it was (mostly) fun, because game is packed with many different minigames, so it wasn't repetetive.
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.
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.
Champ 2 in 2s currently, it's pretty much the only thing I play.
Actually I've only been playing casual of late, I find the toxicity a bit lower there. You might actually have a couple of decent games with a nice team mate.
But I've been playing since it wad kinda new, I was among the ones who had to pay 20 euros just to buy the game on pc. I played it with a DualShock 3 with an XInput wrapper. When I started I didn't even have a DualShock so I played mouse and keyboard. And I think some of the hours are just having the game open but not playing.
As much as Monster Hunter is my favorite series of all time, and I have about 1600 hours combined total over several games, it's still not caught up to my total of over 2000 hours in Warframe. Love that game to bits but yeah I think I played it enough.
Most other games I play, that I played a lot, hover between 100 and 300 hours each.
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.
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)
One of the Paradox strategy games by a comfortable margin. It'll be one of the Crusader Kings or Victoria games. I've got a weekly game night with a couple of friends that was originally just CK, but has for a while now been working extremely slowly through a megacampaign. You can take the end of Crusader Kings and make it into a mod for the start of Europa Universalis, then repeat the process into Victoria and then Hearts of Iron. You need to set some rules for yourselves, because an experienced player doesn't need even a third of the CK timeline to demolish all AI threats, but the games are already good roleplaying fodder anyway so you can set rules that play into that. We're currently about three quarters of the way through Victoria
Outside of those, Noita or Deep Rock Galactic. For a while, those plus a podcast were my go-to "zone out brain off" relaxation, so the hours racked up
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.
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.
Hang on. WoW came out in 2004. So in 6 years you played 3 years in-game? 12 hours a day, every single day for 6 solid years? Were you on disability? Because after sleeping, that doesn't leave much time for work or school.
2 of those years were after I finished school and was just living rent free at home and gaming full time. During that time it was easly more then 12h a day. Though, a lot of that was just being logged in and idle while chatting on teamspeak or doing administrative work for the guild (we ran our own webserver out of a friends house for our forum/dkp system, etc). That's how I learned programming.
There was also some account sharing, which was literally required to get to the top of the vanialla PvP ranking. Games were built different back then.
Definitely WoW for me back in the day too, in the 400 day range across my main and alts. These days No Man’s Sky in the 400 hour category. Things change when you become a parent, but I still try to find time to play games.
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.
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
