That would be Elden Ring. Spent 200+ hours on that game (might sound like rookie numbers but that was my first open world game, was just a casual gamer before that).

Easily 10k hours throughout the Diablo series.

Over 750 hours in Total War: Warhammer II.

Probably 2,000 or so in Guild Wars 2.

Call of Duty Modern Warfare

I'm over 10k hours on FFXIV, been playing since launch. Could get an exact answer when i get home. Next closest is Skyrim with around 1,500.

Edit: it's over 14k hours, more than 584 days worth. It'd be much more if I had more time the last two years but I can't do much than dailies with a 15 month old!

Looking at 600+ hours in Rimworld, and probably even more in Dwarf Fortress but 200+ since the Steam release, it wasn't tracked before.

Stellaris almost 600 hours and Cities Skylines, around 400 h. Damn!

Gtav on ps3 was a blast.

Microsoft flight simulator thanks to slow internet and 200gb updates every time I play.

Continuum. I have more than 10 thousand hours on my main account, 3 thousand more on alts I do not have access anymore. Most of the time was afk or just being online since it had a chat and very lightweight. You can see top players by usage time on the trenchwars server website.

I have 1000+ hours in Forza Horizon 4 & 5, mainly due to weekly FOMO (new car every Thursday).

~800 hours into PAYDAY 2

~1800 hours in various sim racing games, assetto corsa, project cars 2, dirt rally/DR2, rFactor2.

And some ~300 hours in Stationeers

Haven't checked in a while but I think my personal record is 1400+ hrs in Europa Universalis IV.

totally accurate battle simulator, i have a really strong morbid fascination ngl

My sister has more than 1000+ h in Sims 4

World of warcraft. Still true. I only played up through Crusade even. But it ate literally dozens of days of my life. I wouldn't say I regret that, as it was a learning experience for me. But I would definitely not have played wow if I could go back.

EverQuest 1. Diablo 1,2,and 3. Cities skylines. Forgot about terraria.

The Elder Scrolls Online

1. RDR2 - 2,225 hours
2. MGSV - 1,388 hours
3. TW3 - 645 hours

I'm sure SMW is the real 3rd. place, but I don't have the numbers.

Breath of the Wild. I put about 300 hours into it.

Ultima Online for sure. Glad the time wasn't tracked...

I would guess I have multiple thousands of hours across the Halo and Pokemon series. My highest played steam game is dead by daylight (gross) at 1k hours. Deep Rock Galactic and PUBG are at around 500.

Guild Wars 2; I'm at 6-7k hours or so. Been playing a lot less lately; I'm not sure if that's the recent content, or if it's me getting tired of it. I don't have a ton of objectives I'm interested in completing at this point; some "nice to have"s, but at this point any character or build I could possibly want to play, I have just about everything I need for. Mostly find myself logging in twice a week to do guild night with friends, and that's it.

Otherwise, GTA V, which surprises pretty much everyone I know except the friends I play with. It's just such an easy game to spend hoursblowing each other up or racing around or whatever in; really a fantastic game to play with friends.

AOE II was my childhood. I played that game for years.

Quake Champions for sure. Best competitive shooter I've ever played (and I've tried all the popular ones), great option if you like movement & aim centric games

1200 hours on Halo The Master Chief Collection on steam. And absolutely countless more on Halo Reach on the Xbox 360.

Either Sims or Transport tycoon Duluxe

Minecraft. I spent a lot of time on it, especially when playing with friends on my server.

Monster Hunter

Mario Kart.
