Games

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

Rocket League, by far. 1500 hours or so.

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.

KSP

Rimworld

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)

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.

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.

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

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.

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

World of Warcraft and then Final Fantasy XIV.

And it's not even close.

Elite, the original one, on Commodore 64.

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.

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.

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.

Arma 3

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.

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

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

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

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'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...

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.

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.

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

The Binding of Isaac

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

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.

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.

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...

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

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

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.

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

Stardew Valley and Core Keeper ;)

DotA2 and possible WoW next.

Warframe, by a big margin.

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

Kerbal space program

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

Maplestory and Warcraft 3 almost certainly hold the first two places from an age gone by, but I don't have numbers for those.

For games that I do have numbers for, Anno 1800, Stardew, and Total War Warhammer (especially if you combine the trilogy).

XCOM: War of the Chosen

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