Games

Guild Wars 2, so far I put 4,800+ hours into it.

I like that it has so many kinds of solo and group content that I can just do whatever I'm in the mood for that day.

Rocket League

Garry's Mod. Basically a gateway drug to hobby animation, and in some ways not so far off from the modding tools used to make it.

If you've watched stuff like Heavy Is Dead, they're usually made with it. Some more professional-looking stuff is instead made in "Source Filmmaker".

Rocket League

Somehow ctrl+f failed to find this one, but Path of Exile is probably my drug of choice there. While I raked in 1k hrs with Dota2, I'm not sure I"d recommend it unless you really want to sell your soul to MOBA life. And it's not quite to 1k yet, but honorable mention must go to Satisfactory as it's well on its way to being game #3 in the 1k+ list with me.

The Binding of Isaac

Elite Dangerous. Well over 1,000 hours, especially with friends to explore the black with. Hard to get into, but it has so much stuff to do. It made me passionate about space! (And it's always fun reading articles about a far-flung star and thinking "hey! I've been there!")

I have one game with 1000+ hours and that is Squad. It's the only online game I play anymore as it is the only game that has teamwork/communication (it takes be back to Battlefield 2 days) and none of the shit like battle passes etc.

My gaming habits are just playing lots and never finishing anything... but I have fun still.

I'm closing in on 2000 hours, and it's such a great game if you like challenges and discovery.

I started playing it after one of the devs said, "I don't think anyone will ever make another game like it."

It's a terrific implementation of a very pure concept.

I really hope that, despite the development challenge it may present, "noitalike" becomes a thing.

I think it's an engine that would integrate really well with ML world/asset generation, too.

Rocket League cracked that for me, crazy ceiling on that game.

Crusader Kings III is gonna crack it eventually…

Rimworld, and Football Manager (although they last one I played is 2020)

Tetris.

A long time ago now I spent over 10,000 hours on world of warcraft. I wouldn't really recommend getting into it now though, I think the magic is gone.

Team Fortress 2. There's just so many different ways to play the game with its combination of classes, weapons and game modes!

I think Destiny is the only game I ever put over 2,000 hours into, but Factorio might take the crown soon - 1800 and counting.

If you like space games, X3 and X4 can probably eat up lots and lots of your time. Space Engineers if you're less interested in flying, space economics and creating a supply chain (which X lets you) and more in gathering materials and creating all sorts of weird, funny or actually amazing stuff. SE is probably better played with at least 1 other person, possibly more, while X is exclusively single player.

Grand Strategy games can also obliterate your free time. Civilization 5, any Total War game. Hell, Age of Empires 2 can have very long matches if you play on huge maps and people have loved that game for over 20 years.

You can also go for Fallout 4 or Skyrim with extra content mods, like dungeons, quests or areas.

Personally, I'm just past 400h on Palworld, so I'd recommend it as well. I've played from start to "finish" some 4 times by now. Official servers will be wiped sometime in December, possibly with a new patch arriving, but you can always play single player and even invite a friend to play on your local save and never lose progress (unless the save gets corrupted, which can happen).

BeamNG.

I just can't stop crashing cars into things in slow motion.

I have around 1700 hs in Destiny 2, and close to the same in Bloodborne. Over 1000 hours in the last 2 monster hunter titles. I've replayed resident evil 4 and castlevania sotn dozens of times.

So those are my most played games

Team Fortress 2

Sims 2 Skyrim Stalker franchise (including mods) Doom 2 Vrchat Arma franchise Halo franchise World of warcraft .... I may have a problem.

Monster Hunter: Not all at once of course, but it's a game I keep coming back to. A friend in college introduced me to it on the psp and I was invested. I've had some version of it somewhere since, and I don't think I've ever removed it from my psp either.

Overwatch: This is from before the change, but it became a comfort game. There were no chats, and I didn't have to be in voice chat. I was low level (bronze), but I was content. I still play here and there, but I may get a match or two in before I leave out. Back in the day I could play for hours.

Ark.

nothing will ever top my smash bros melee hours. I could start now and I simply wouldn't be able to do it even if I picked the game I already have the next most hours in. I am also entirely unlikely to add any hours to melee, but it still wouldn't be feasible.

World of Warcraft

Dark age of Camelot. 6000 hours on my main character. I prefer not to think about how could life be different now if I had not started this game…

Satisfactory

Grim Dawn (currently playing Community Season 7! check it out @ https://grimdawnleague.com/, Dead Cells and Terraria (and most of that time unmodded - i just love building cozy or not so cozy homes).

I've only got a few. Several of them don't really track hours, but I know I've put over 1000 into them. Games like Super Smash Bros. (Melee, Brawl, and 4) and Rock Band 2.

Other than those, the only one I've measurably put 1000 hours into is Skullgirls, but Guilty Gear Strive will likely get there in a few years. Skullgirls is a game with so much depth that I can't imagine ever getting bored of it. If anything, I'd just lose motivation because I can't see the path to improving, but I'll definitely never see every permutation of strategies you can employ by combining characters together. Guilty Gear Strive has so many creative ways to use its expanded Roman Cancel system that any Evo highlight reel is full of creative ways out of situations that you've never seen before.

In descending order: Skyrim Fallout 4 Starfield

Morrowind is a game that has extreme hours too, but not sure if it is 1000+ (yet).
