Games

Factorio, it's fun from the first minute but you'll still be learning new things after 1000 hours.

cracktorio

Project Zomboid, Rimworl, Dwarf Fortress, Stellaris, Starsector...

I've been playing Tf2 for over 1.5k hours now. I recommend you to try it out There's a reason why that game from 2007 is still not dead.

Warframe. Inching closer to 3.000h currently.

It does come in waves, but every once in a while I go all in again and lose myself in the infinite things you can do.

The only two games I have that I've put more than 1000 hours in are Factorio and Rimworld. I'd highly recommend both.

Per my steam library:

Factorio: 3,375.4 hours

Dyson Sphere Program: 2,505.9 h

Stellaris: 2,236.6 h

Terraria 2,629.9h

Skyrim: 1,239.5 h

Dungeon Defenders only has 600 hours on Steam, but I'm well over 2000 hours between Steam and PS3/4

I've also got a few thousand hours in Just Cause 2&3, as well as several Gran Turismo games and Forza Motorsport games. Morrowind probably has 2-3000 hours, oh and I'm not allowed near Sid Meier's Alpha Centauri anymore.

Secret of Mana and Chrono Trigger are probably up there as well since I'll replay them every decade or so.

Not a favourite anymore but still beats my second most played games by a factor of 4... Warframe was fun at the beginning and really clicked at about 200hrs. I left after about 2200hrs because I burned out but it still has a place in my heart.

There was a moment in my life when I thought that perhaps I was outgrowing games... that they were just not really designed for the entertainment of adult human beings in a way that could satisfy me. Not one of my old stand-bys could, as you said, "scratch the itch" or provide "the same enjoyment that it used to." I found myself spending more time with films and books.

Then I got into FromSoft games and indie titles, and within a year I realized games still held incredible experiences for me. I hadn't outgrown games. I had only outgrown the bland slop represented by most AAA releases, and especially by online multiplayer releases. Personally, I'd recommend giving up on looking for a new 1000+ hour obsession. Instead I'd recommend seeking a broad array of 10-100 hour loves. If you haven't already tried them, for me a love of gaming was saved primarily by: Dark Souls, FTL, Spelunky, and Hollow Knight.

Monster Hunter. The first one I played, MH4U back in the 3DS days, I put 1,000 hours into. That was nearly 10 years ago, and I'm still playing the franchise to this day. Currently finally going through the Sunbreak expansion of Monster Hunter Rise on the PC, and noticing a marked improvement in my mental health over playing other games.

Deep Rock Galactic

Elite Dangerous is my go-to lately.

It's different to most other games, by not being goal-oriented except for the goals you set for yourself. No main quest line dictating progress. No mandatory tasks. No win condition. Instead, it drops you into a simulation of our entire galaxy roughly 1300 years in the future, where humanity has mastered hyperspace travel and spread through hundreds of star systems.

(To give an idea of the simulation's scope: Around 85 million systems have been recorded by players so far, and those are a vanishingly small fraction of what's out there. Space is big.)

I like that it offers a variety of activities to fit whatever mood I might be in on a given day. I can hunt pirates, mine asteroids, engage in a bit of piracy myself, find and collect bio samples, infiltrate rival settlements, venture into vast unexplored areas of space, discover Earth-like worlds that nobody has ever encountered before, defend humanity against hostile forces, photograph beautiful stellar phenomena, rescue stranded survivors, customize and finely tune my ship to perform beyond its original specs, team up with friends, pledge to a political power and expand their influence, or chill out as a space trucker and haul cargo to earn enough money for my next upgrade. It can occupy all my attention, or just be relaxing entertainment while I listen to music or an audiobook.

It's an MMO in the sense of having a large game world (galaxy) shared by all players in real time, but PvP is optional. One mode exposes you to other players, while another limits you to NPC encounters. You can switch between them at will.

One warning: A space ship has more than a few controls to learn, and they're better suited to a game controller or HOTAS than a keyboard and mouse. I use button combinations for almost everything beyond basic flight controls, since there aren't enough buttons on a controller for everything.

X4 Foundations... This sucks people life: you start a game when the sun goes to sleep, one second later the sun wake up 😅

I'm amazed nobody has mentioned Kerbal Space Program (first one). That and TF2 are my most played

No Man's Sky. A foot deep but a mile wide.

Factorio

The Factory Must Grow

I’m almost 100 hours into my new space age save, and I’ve played nearly 1k hours since I bought it 5ish years ago. By far one of the most enjoyable games I’ve ever played and I highly recommend it to everyone who enjoys sandbox games

If you're a Destiny refugee, the most obvious answer is Warframe, which just keeps on getting better and better.

terraria for me. i keep managing to find new stuff over a thousand hours later.

"Has this item always been here?! no way. REALLY?"

lol the problem with Destiny is they turned it into a treadmill and stopped putting the work into character and level design.

Elden Ring can easily take more than 100 hours on your first playthrough, and different builds significantly change your play style.

BG3, similar deal. Subsequent playthroughs are probably going to be accelerated, but there are a bunch of different story choices you can make that feel different, the party members have their own story lines, there's a special custom character called Dark Urge that's intended for a later playthrough that has it's own twist, and you can change the strategy of encounters a lot with different party constructions.

Rimworld calls itself a story generator because you're going to fail and have people die and whatever, but every game plays out different, there are a good couple scenarios, and there's expansions and mods you can add on top of that for variety.

Just the first couple that come to mind. I'm not near 1000 hours on any of them, but they all have a lot of content.

L4D2. built a new computer for that game specifically after loving L4D. super fun arcade shooter that will never be uninstalled from my computer.

Trackmania 2020. Great example of a game that is simple in concept but super deep in skills that you can both play super casually at your own pace or super competitively. Plus there is a great community and endless content to play.

Factorio: 2344

Path of Exile: 2736

Rimworld: 2191

Kerbal Space Program: 1071

I have a bunch of honorable mentions in the several hundred hours ranges that are only not 1k+ because I have severe ADHD and something else became a hyperfocus before they hit that point:

Backpack Hero

Ark

The Last Spell

Timberborn

Factory Town

Dyson Sphere Program

Loop Hero

Brotato

Satisfactory

Path of Achra

Against the Storm

Desynced

Mount & Blade II: Bannerlord with some mods took long enough to give up for me.

Stellaris

Oxygen Not Included- very detailed colony sim where scientific things like heat exchange, air pressure, etc. are essential for survival. I swear, my next file will be perfect...

Path of Exile.

I'd say I'm a fairly mid-tier player, get better with each season I play, the breadth of mechanics and depth of complexity is mind breaking. I've only played like 2000 hours though, I'll get it all figured out eventually... Right?

If it clicks with you Monster Hunter (World+Iceborne’s a good starting point) can easily eat up hundreds of hours of your time grinding and doing endgame content, especially if you have a group to play with.

Mine are:

Any Fallout or Elder Scrolls

Diablo 2 or 3

Stardew Valley

Borderlands 2

And I never consider it a real game, but I do sink the most hours in Hearthstone. I've been playing it almost daily for the past ten years.

Team Fortress 2

Dark Age of Camelot

Sims 3, Skyrim, Fallout 4

Why do they have to be 1000 hours? If you’re getting gaming fatigue you’re not going to fix that by sticking to the same genres you always play. Go onto Steam/gog/eshop/etc during the Black Friday sales next week and buy a big pile of 40 hour games for $3 each

(Mine is FFXIV, to answer your question)

Slay the Spire

Kerbal Space Program

I’m well above a thousand hours on the first game. Then all my flying sims (MSFS, Xplane, DCS, Elite Dangerous) also have a very high hour count. But for civilian airliners most of those hours are spent AFK in cruise.

Regarding the question itself, Starbound and Minecraft. Maybe Final Fantasy XII if I was to play it multiple times, as I take at the very least 100+ hours to finished it, and 250+ if I'm not in a hurry.

But regarding gaming fatigue, perhaps it could be a symptom of playing too much of only a handful of game styles? If you wouldn't mind, may I suggest to check some smaller games in length and scope, specially indies? Those tend to be rather diverse in their scopes and executions.

Factorio, Warframe, Minecraft, Dota 2. However, the only two I'd still recommend are Factorio and Minecraft. Warframe's grind seems to have finally burned me out for good, Dota 2 is bad. You're not gonna have fun with Dota 2. The game concept is good, but like most competitive online games, the community fucking sucks.

In addition to Factorio and Minecraft, try Voices of the Void, The Long Drive, WEBFISHING, and Balatro.

Edit: oh yeah, and personally I have both Sims 2 and Sims 4 w/ all DLC (yeah, I toootally bought all the dlc) installed on my steam deck. Both fun games with their own ups and downs. Sims 2 is great vanilla, Sims 4 is great when heavily modded. Don't bother downloading the F2P version of Sims 4 from Origin if you're wanting to mod it with stuff like sacrificial's mods. Those'll break with every major update (and sometimes minor updates too!) and you can't pause updates anymore. So, you'll have to find alternative methods.

Dota 2.

I've played Dwarf Fortress, Stellaris, yet I still find Dota to be the most complex game ever.

It sucks that it's a multiplayer game, and you need people to play it well with you, but when it works, it's amazing.

Everything in it has layers of usability, usually componded by the everything else in the game - hero abilities, items, map, neutrals, even the stupid trees play a large role in the game.

I've spent hundreds of hours studying the mechanics, and I still don't grasp everything.

I played a lot of DotA too, but that doesn't have a playtime counter. But I have over 3000 hours in Dota 2.

My second favourite game is OpenTTD. It's just so satisfying to optimize the train network and add another 100 trains to it. I've tried Factorio, but for some reason that did not scratch that itch.

Or some roguelites, like Slay the Spire (or the Touhou: Lost Branch of Legend), Synthetik (haven't tried second one yet), they are always fun.

I don't think I've ever played a game more than 200 or 300 hours.

Final Fantasy XI. I'm almost exactly 1,000 hours into it, and only halfway through the storyline. I haven't even touched end-game content. I'm playing on a free private server called HorizonXI that is well-populated and feels more like the game when it came out versus the modern day solo experience.

Morrowind. Although it's more like play a few hundred hours every five years for me.

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.
