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

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.

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.

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.

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

Probably 2048 which is just a fidgeting toy for me.

Rocket League, by far. 1500 hours or so.

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.

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)

steam says I played Fallout 4 for 436 hours, but that seems very high. not sure if that count is accurate.

Old School RuneScape, Gran Turismo 5 & 7, The Crew 1, 2 & Motorfest and I think Midtown Madness 1 & 2 are also high on my list of most played games.

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.

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.

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.

DayZ, I have around 3000 hours in it.

Guild Wars 2 has been my theme park MMORPG of choice on and off for the last 12 years, with >2500h. I have also spent ~1000h on Elite Dangerous.

Elite, the original one, on Commodore 64.

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

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.

In no particular order:

• Ragnarok online
• Darkspace
• Monster hunter (multiple games)
• Dj max (multiple games)
• Garry's Mod
• Aliens VS predators 2 (1998)
• Halo
• Warframe Phantasy star online (and 2) Path of Exile Morrowind probably.

The Binding of Isaac

Arma 3

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

My top four on steam are:

• Garry's mod - 2800 hours
• CS:GO (CS2 now) - 2100 hours
• Terraria - 1000 hours
• Team Fortress 2 - 555 hours

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

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

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.

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...

Stardew Valley and Core Keeper ;)

WoW, CS 1.6, Warframe, and ARK

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.

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.

DotA2 and possible WoW next.

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

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).

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

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...

Skyrim and Satisfactory.

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

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.
