Games

That I know of (3000+): Team Fortress 2

Probably(500+): Super Mario 3, or Apotris

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.

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

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

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.

I'm a bit ashamed of it, but Overwatch, I really enjoyed the multiplayer and played with some cool people I met in game. Stopped playing when OW2 released.

My second most played game is Destiny 2.

Maybe something is wrong with me...

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 as I get older I game less hours, so most of my games on this list are older. LoL, wow, Dota 2, modern warfare 2 (2009), Wingspan(online boardgame), PubG battlegrounds, counter strike 2, terraria. I haven't played fps, wow, or dota for years, but they still dominate this list. It's funny because if I made a list of my favorite games, it would include almost none of these, except terraria.

When I played on PC more EverQuest, counterstrike, TF2, wow, Skyrim

After playing more on console ff14, elder scrolls online, pillars of eternity 1/2, and souls games (ds2, ds3, bloodborne, elden Ring)

I also like to play Indies and smaller games but those are the ones I keep going back to

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

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.

Probably Warcraft Rumble.

Arma 3

KSP

Minecraft, and the number is still growing.

Craft the world, Valorant and AoE3

STALKER and The Elder Scrolls probably hold the record. I may have wasted even more time in my life on World of Warcraft, but I feel like that doesn't count since you're just in a fucking trance for several years until you finally break away.

Terraria

Minecraft, Factorio, Satisfactory and Dyson Sphere program have the most real playtime, but idle games have the top slots.

Factorio.

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

EverQuest was my jam back in the day. It ruined highschool for me. Nearly 5 straight years of farming and raids.

I wouldn't do anything different though. I met some awesome people that got me through the awkward years of high school when the internet was still somewhat new.

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)

I put the most hours into Awesomenauts during college... really miss games that time

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

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...

It's either the Sims or Animal Crossing.

The Binding of Isaac

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.

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

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

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 >_<

Edit - ...Ark owned my life for a bit, too:

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

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

Warframe, by a big margin.
