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

Probably GTA Vice City back in the day. So much room to just dick around and kill random people.

GTA series in general, and GTA V in particular.

Soul Sacrifice

I’ve yet to come close to my record of 800+ hours in Rust with any other game.

XCOM 2

Got around 300+ hours into Borderlands 2 and around 600+ into Warframe

Acorn Revs. can't tell you the hours, thousands would be my guess. Elite: not quite as many hours. Discovered the save file format.

Guild Wars 2 by far, 10k hours. Followed by Wow and Civ 5.

Hollow knight ~110h

1. Doom I and II with who knows how many hours since Christmas 1996.

2. Minecraft since 2011.

3. Binding of Issac with close to 1k hours.

4. Factorio with 850+ hours and currently rising.

I had over 10,000 hours of Call of Duty 2 (2005 version). 4000 hours of the first Call of Duty Modern warfare and currently have 3600 hours of Csgo. It’s common to run into 6-8000 hour accounts in Csgo.

Anything less than 1000 hours in Csgo is considered new to the game still.

This depends on what you define as in game. According to Steam, I've spent the most time on NGU Idle at 3306 hours, but a large amount of that was spent with the game running while I was asleep or at work. For Steam games with the most hours, I've spent 840 playing Path of Exile but that doesn't include the 200 or so hours playing the standalone client. This is followed up by 440 hours playing Terraria (which doesn't include console version hours), and Realm of the Mad God which I have 325 hours playing.

If we include MMOs in the mix, I've easily clocked 1500 hours playing both World of Warcraft (between Classic and Retail up to and including Mists of Pandaria) and Guild Wars 2 over the years.

Funny enough, I wouldn't include any of these games in a list of my favorite games other then Terraria, so that's good to keep in mind :)

Monster Hunter

Terraria and Path of Exile

DS1 to DS3, I lost count of the hours.

CounterStrike. Haven’t played in years but there was a while when it consumed my free time.

Planetside 2

10 years and counting

Starport GE

15 years and counting

On steam it's dota 2 with about 3k hours but really my most played game is the old f2p Combat Arms. I nearly exclusively played that game after school to bed for like 4 years, I probably had over 6000 hours logged. Still talk with the friends I made there a decade later.

Swtor

Grim Dawn with 800+ hours. Slay the spire is 2nd with 600+ hours

Team Fortress 2 with over 1,200 hours. I've been playing it regularly for over a decade, so the hours have added up

Any of the Championship Manager games.

Quake II consumed about a decade of my life. Alright, 15+ years.

4000 in arms 3 1000 in TF2 Around 2000 in osrs

Jesus Christ, didn't realise it was that bad. I just wish I was any good at any of them

I'm at around 1750 hours playing The Binding of Isaac and I'm not done with the game......

I racked up about 9000 hours in WoW before quitting, bit over 3000 hours in Runescape.

Because I've been playing on and off for around decade - if not a little longer - on xbox360, I'm going to say Borderlands.

I still have a ton of content left in the game since I only had the zombie island and underdome riot DLCs until three years ago and even then still had only really focused heavily on my main account for most everything in game, leaving my playthroughs with the others far behind in the dust.

CSGO.

I dont know exactly but I have around 300 hours in every soulsborne game inkluding elden ring. Such good times.

Top 3:

1. Minecraft - Probably over 1000 hrs
2. Stardew Valley - 491 hrs
3. Sims 3 - 425 hrs

Definitely Morrowind! The Elder Scrolls III. Oh, I might actually start it back up again at some point.. Maybe one should try the Tamriel Rebuilt mod.
