Historically:

• XCom - Enemy within (with Long War mod)
• Kerbal Space Program
• Crusader Kings 2
• Rimworld

Terraria. I don’t know why but the progression in the game feels so damn addicting. Mods add onto it by alot too

DotA2 and possible WoW next.

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

Factorio 5k+ atm

Unless we count pokemon, played that to death when I was younger, would be willing to say I have “young person time” amount of hours in the Gameboy versions.

The Bethesda RPGs: Skyrim, Morrowind, Fallout series (although most of the hours probably into NV, which wasn’t actually Bethesda).

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

I quit a couple years ago for good, but my main account on RuneScape was created in classic as a kid. I had about a year and a half of PLAY time on the account, mind you the vast majority of that was back when you had the hard 5 minute afk timer, so that was at least moderately active play. Then if you add my ironman account I have nearly 1/15th of my whole life logged into RuneScape. I don’t regret it, my whole friend group as an adult stem from those friendships I made online during my young teen years. However, as a modern game as much as I have a place for it in my heart, I found I had more of a negative addictive relationship with it. Maybe I always did, but I didn’t feel a negative mental effect at a young age.

I have over 1k hours in The Long Dark and 7 days to die. Around 500 in space engineers, darkest dungeon, binding of Isaac, enter the gungeon, grim dawn, and satisfactory. ~300 hours in ToME4 and Caves of qud each. That’s just steam stuff though, there are a lot of games that I know are up there that aren’t on steam.

I’m sure I have at least similar numbers to 500-1k if not much higher in Diablo 2-3, and I’m sure more than a few thousand in wow though I lost my og account after wotlk because I forgot the details when I quit so I’m really not sure.

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…

Rimworld

Factorio.

World of Warcraft and then Final Fantasy XIV.

And it’s not even close.

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

If we’re counting every Pokémon game as a single one, then that. Otherwise, probably Skyrim. I must have like 2000+ hours across all of its versions.

I was gonna check my Steam library for the numbers, but the real answer probably is Shattered Pixel Dungeon on my phone.
