They've reset mine twice before many years ago. I'm sure Minecraft is my top overall. In steam it says Metal Gear Solid 5 is my top but I would leave it running sometimes for the research to finish. Second is Garry's Mod. I played that A LOT when I was younger.

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.

I probably have years of playtime on Super Smash Bros. Melee for Nintendo GameCube

Borderlands 2

Idle Wizard 6k+ hours

NGU Idle nearly 4k hours

MHR Sunbreak 1k+ hours

BattleTech 1k+ hours

MH World 800 hours

Those idle games running in the BG sure racked up the hours. Ran them for more than half a year before I realized I was just wasting power for something senseless.

CS:GO 5000+ hours wasted in my 20s

Dead By Daylight has consumed more of my life than any other game at 1600 hours (since 2018), and that’s still rookie territory. I’ve never been able to commit to a game for very long, maybe 40-80 hours max and that was only two or three games in my life. DBD just has a hold on me.

I believe the game I have the highest number of hours in is League of Legends, but I don't know the exact amount because at a certain point riot changed their API and the tracking site I used reset. But the highest it was ever at was 2,376 hours. The highest games I currently can still track are Skyrim with 789.5 hours and Skyrim legendary edition at 241 hours, then Stardew Valley with 953 hours, Fallout New Vegas with 612 hours, and Final Fantasy 6 with 557 hours(this was one campaign.). Everything after that is sub-500, but I give an honorable mention to Dark Souls 3, at 441 hours.

Risk of Rain 2, man. My absolute favorite game of all time.

What, recently?

Historically, Destiny or Borderlands, probably the latter. But lately, I'm spending all of my time in Factorio.

I haven't looked at the hours stat; it'd probably only depress me.

7 Days to Die. It's an incredibly underrated game. I'd describe it as Minecraft, but for adults.

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

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.

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

Path of Exile, around 3k hours and it is still my favorite. Every 3 months you get to play again with a different twist, and Path of Exile 2 (just an update, but a huge one) is being worked on and will likely release next year.

Easily 10k hours throughout the Diablo series.

Either skyrim or oblivion. probably Oblivion. It's the most immersive game world I've encountered. Emminently replayable.

Minecraft. 2.5 kilo hours

Probably Terraria

Call of Duty Modern Warfare

Either Sims or Transport tycoon Duluxe

The Elder Scrolls Online

League of Legends, no doubt (and no idea how many hours across my two main accounts). Just... yikes on a bike, that one.

Other tops probably Sims if I can count all the different games. Stardew and animal crossing are up there as well, I'm sure.

Old School RuneScape, by a lot!

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!

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

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

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

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.
