Moving to: m/AskMbin!

While it's hard for me to come up with an ALL TIME favorite... playing Doom 2016/eternal is one of my greatest pleasures in life. Just simple mindless hack and slash that can get MUCH more difficult if you want it to

Disco Elysium

Being totally honest, I don't think I can just settle on one game like that. I play different games for different reasons, and what genre/titles I've played the most has varied a lot throughout my life.
Up there, however, is Dark Souls, as well as League of Legends (despite all the issues I have with it, it's sucked me back in for over a decade now).

Jet Set Radio Future on the original Xbox.

I just love everything about it.

Final Fantasy VII

I always end up going back to the first Half-Life; everything in that game is very well made.

Elder Scrolls IV: Oblivion or GTA 4. 100% nostalgia picks since these are the games that I played endlessly as a preteen into high school. I would maybe throw Pokemon R/B/Y in there too since those were the games I played endlessly until I was old enough to start detasseling and buy myself GTA 4, Oblivion, and an Xbox 360

As I've gotten older and have less time to commit to competitive gaming, cooperative gaming still lets me enjoy challenging multiplayer experiences without having to worry about ELO or keeping up with the current meta as much.

As much as I love Helldivers (and I am very excited for the sequel coming out later this year), Deep Rock Galactic is undeniably the champion of the cooperative gaming genre. You can jump into almost any lobby of random players and be rocking and stoning together instantly. Deep Rock Galactic features many game mechanics that just naturally result in cooperative play, without the need to rely on voice or text communications (though, voice and text are available and used).

Not to mention that the devs are really really amazing. Seasonal updates always come free of charge. They have a battle pass system that is 100% free that just rewards cosmetics. If you don't get battle pass cosmetics by the end of the season, you can still earn all the cosmetics at a later date. The only DLC on offer are cosmetic packs, which are really cool, but the cosmetics you can earn in-game are also really cool. There's no pressure at all to spend more outside just buying the base game. I deeply appreciate them and how they conduct business.

Like some already said, I too love Mass Effect, Dragon Age, The Elder Scrolls, Zelda TP and Stardew Valley. It's hard for me to chose a favorite game… There's a few of them I equally like, and it kinda changes depending on my mood.

Saints Row 2 is one I haven't seen mentioned yet. There's always something fun to do in this game and it’s hard to get tired of it. The map is packed full of interesting stuff, feels bigger than it actually is. And without writing a novel about it, I like the story a lot. It's a perfect balance between wacky and serious, plus the characters are great. Truly underrated game imo. Shame what happened to the series…

That Dr. Mario vs Tetris game. My mom would bust it out and we’d have competitions way past bedtime because she was addicted. So some good childhood memories attached to a fun little game.

Star Control 2. My son and I just started another playthrough.

Holiday Island. And Transport Tycoon Deluxe...

Trials of Mana. Actually the whole Mana series were completely unique and very innovative when they first released. But the combination of story telling, party building, and combat system still hasn't been topped for me. The games are something I always have ready to emulate at all times. Fingers crossed they decide to remake the rest of the Mana series. Legend of Mana needs some love even though I remember most people weren't really keen on building their own world.

The Tales series was probably the closest before the switched from 2D to 3D. The switch, I thought, took away a lot of what made them stand out from other jrpgs in the market.

My close 2nd is Legend of Dragoon since it actually changed the combat system in a really meaningful way. Legend of Legaia also did something similar but I thought the storytelling was better in Legend of Dragoon.

Soul Sacrifice still needs some love. It's only downfall was releasing on such a niche system like the Vita. It actually moves the MH formula forward in a really interesting manner by forcing you to make really interesting choices in the story.

Asteroids. I shudder to think how many quarters I spent playing that game. Sometime I’ll have to see if there is some retro arcade out there where I could go play it again.

Hard to choose one, but maybe I'd say Kerbal Space Program 1. It had a really profound impact on the way I understood the world, space, physics, and gave me one of the best feelings of pure exploration. It was amazing to drop into progressively lower orbits around a new planet or moon before finally landing and walking around.

Pokemon Sapphire

System Shock 2

Many games come close for me... Mass Effect, Zelda Link to the Past,, Factorio and Homeworld would round out my top 5 for instance. But System Shock 2 was my first immersive sim game. It started a love affair with the genre that I'm still trying to scratch 25 years later.

There were many spiritual successors, with Arkane's Prey being the closest approximation I've found. Nightdive just released the original System Shock's remake a month back, so the wait for them to announce they're giving SS2 the remake treatment is torture.

I've played a lot of the games on this thread and more that haven't been mentioned which deserve to be recognized, but for my experience The Binding of Isaac: Rebirth goes at the top.

There are others more nostalgic, others with more acclaim, but I always come back to Isaac. The RNG, art, humor, and item combos made that game stick to me like nothing else. It has just a little hit of inspirational game design that speaks to me.

@GeekFTW Duck Hunt and Zelda A Link to the Past on SNES. Core childhood memories with family.

ICO

Dishonored, I absolutely adore that game, and it still looks so good because of the art direction they took with it. Funny enough, it was the same art director as Half Life 2

Pokemon Mystery Dungeon Rescue Team DX. The originals were the games that made me realize gamrs could make me feel things, and DX is literally just them but with QoL changes.

Is it even possible to pick just one?

Several of my favorite gaming experiences are one-time, non-repeatable. Solving the Return of the Obra Dinn is up there, but it couldn't possibly be my favorite game because I can never experience it again.

Playing Dark Souls for the first time is the same thing. Discovering the world, finding the intricacies of the interconnected map, struggling with and overcoming challenging areas and bosses. The relief of unlocking shortcuts and the amazement at the maps connectivity. It was the first game of it's type I played, and it was phenomenal, but coming back to it never matches that first playthrough. And let's be honest, the bosses feel downright mundane after having played the later releases.

Disco Elysium affected me in a way no other game has. Its themes are so relevant to me that it struck me on a very personal level and it was an incredibly cathartic experience that will stay with me forever the way any great book would. I actually found it more enjoyable the second playthrough too, however, is it really even a game?

I don't know of I could ever say a single game.

Minecraft is definitely the one I've spent most time, probably more than a couple of thousands of hours

Empire Earth is the one I go back the easiest

The Binding of Isaac.

Final Fantasy IX

I just love it. The cast, the writing, the music, not a perfect game but for me a perfect story, a perfect experience.

There’s too many to list but Zelda 2 was the first game I finished. It was a collaborative effort, using a book, but my friend Frosty and I stayed up all night (this was in junior high so this was a big deal) and finished it. Fond memories.

Lots of great games have been mentioned but wanted to include two recent masterpieces:

• Hollow Knight. It's such a fantastic ride, such a rich world, such great characters, and such a terribly sad but somehow poetic plot. Getting that game even today at full price is still a steal.
• VA-11 HALL-A: You're just a background NPC in a big cyberpunk adventure, nothing you do has anything to do with the main plot, you only get glimpses of it, and the story is essentially the mundane life of this person and not much else. Yet it's so rich and interesting and fun! And the music is awesome.

Definitely Dark Souls. I have played DS 1, 2, 3, Bloodborne, Elden Ring, and Sekiro. I only have completed DS 1 and 2 out of them (mostly due to time, with the exception of 3 which I just don't like).

I know the DS1 map like the back of my hand, the mechanics feel natural to me, I feel like I'm being treated fairly and have the skill to complete challenges, and it genuinely feels rewarding for me. I feel good after playing Dark Souls for a bit. Even when struggling with a boss, 95% of the time it felt like I had made a mistake which could be fixed next time.

I’m probably weird when I say Final Fantasy XIV A Realm Reborn. At first a failed game that became a labor of love by the people that took it over. It took multiple years and expansions for it to come to a “conclusion” and the once i finished it, I was very satisfied.

To me it’s similar to the Marvel project up until the conclusion of the Thanos arc. I’m not the biggest marvel fan or much of a Disney fan. I do really respect the courage it takes to throw that many years at a project and trust it almost all the way.

FFXIV feels like that. It has that final fantasy marriage of interesting yet somewhat complex story with a message that makes you think. Its an MMO but honestly you can enjoy it up until the conclusion of End Walker with a couple of friends and some queuing up for the story fights. You shouldn’t have to do any terribly difficult encounters to progress the story and experience the game unless you choose to. The. Every so often you run into a song and get blown away. The game does a great job of usually having each expansion have a visual and music theme and sticking with that without making it feel like repetitive copy paste job.

I almost never like replaying a game or heck rereading the same book. But this game is the one exception where if a friend finds interest, I’ll resub and level yet another job with them and totally enjoy all over again.

Gothic I&Ii

I'm pretty old so have a lot of games I feel terribly nostalgic about, but I'm going to pick a relatively recent one in Deep Rock Galactic.

It just feels like such an absolute triumph of game design in so many ways. I've always had a soft spot for Co-op PvE, and it's just done right. Having a dedicated key to rock and stone (cheer on your teammates) is an absolute genius move for promoting positivity and cutting down on toxicity. Gunplay is good and varied. The feeling of exploration is AMAZING! Probably the game that's kept me going 'wow' when I go to a new place the most consistently after hundreds of hours.

So much respect for the devs who are continuing to absolutely nail it!

Gotta go with Morrowind. It was a pretty formative experience during my early teenage years, and it's one of the few that I boot back up for a fresh run about once a year. Instigating the downfall of the Tribunal has become something of an autumn ritual for me. I know the world map layout of Morrowind better than I remember the layout of some of my own childhood homes.

It's a little clunky and not enjoyable for a lot of people that jumped into Elder Scrolls with Oblivion or Skyrim, but for old school fans, it's still probably the single greatest product that Bethesda has ever released. Fallout New Vegas makes a close second place on that list, but at least in my opinion, Morrowind holds the crown and given modern Bethesda's tendencies I don't expect that to change.

Undertale still holds a special place in my heart after all these years.

It made me care about its characters in a way that no game had ever done before, and few have since. The cool and replayable story, along with a great soundtrack are other things that I like. Only criticism I really have of the game is the questionable graphics, but I've never been the type to care too much about graphics anyways.

Going all the way back to the NES for me, and I'm getting the feeling I'm quite a bit older than most of the commenters here: Super Mario Bros. 3 - best game of all time. :)
