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.
Easily Fallout 4 or No Man’s Sky
Elite, the original one, on Commodore 64.
7 Days to die. 1600 hrs on steam Call of Duty. 1200 hrs on steam
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.
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.
DayZ, I have around 3000 hours in it.
My list of multiple hundreds/thousands of hours include, in no particular order;
- Minecraft (unknown, been playing since browser alpha demo)
- Skyrim (600)
- Rocket League (4000)
- Fall Guys (1500)
- Stardew Valley (unknown, play multiple saves a year on different platforms)
- Vampire Survivors (400)
- No Man’s Sky (1200)
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.
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.
Fallout 4 and Skyrim
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 XI and it’s not even close.
Heyyyy, high five! I’m not sure what my XI playtime is at offhand but I know it could be measured in years.
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…
Aren’t space heaters pretty cheap? Probably didn’t need to add wear and tear to your GPU.
I had a space heater in there, too. It was not enough.
2000 hours in Garry’s Mod, 1300 in TF2. Third place is way behind, Hollow Knight at 180.
