In no particular order:

• Megaman X
• UNDERTALE
• Call of Duty 4 (campaign, never played MP)

I just really like those three games. They're all fun in their own ways and in the case of Undertale it shaped a huge part of my 20's because it was through playing it that I learned to love humanity even with its bumps and scrapes. It kept me from turning into a full on misanthrope.

Honorable mentions go to GTA Online (I have almost 6000 hours in that game total, it's my favorite pastime), Call of Duty Black Ops 2 (multiplayer), and Titanfall 2.

Oh , probably

1. Witcher 3
2. Cyberpunk 2077
3. Something like persona 4 golden? Feels a little like a log jam

Only three is a cruel restriction; I grant myself at least a top four.

• Morrowind
• The Neverhood
• Diablo 2
• Hyper Light Drifter

Factorio Outer wilds Horizon zero dawn

1. Celeste
2. Outer Wilds
3. Slay The Spire

Much hidden gem.

1. Puyo Puyo 20th Anniversary - Puyo Puyo is the greatest competitive puzzle game ever made, and 20th is a massive package of incredible extras to go with it. I made a video just showing off how many cool things are in this game, and got so carried away that it ended up being an hour long. To this day, I continue to have a chip on my shoulder about how everything else Sega has done since doesn't come anywhere close to this game, and so the west has never gotten to see the best of what the series has to offer.

2. Skullgirls - Best damn fighting game of all time. Fast, explosive, with tons of options for flexible teambuilding. It wears its old-school influences on its sleeve, in an era where too many modern fighting games feel watered down. At the same time though, Skullgirls was also so far ahead of its time for having functional online, a training mode more robust than any other game at the time, and tons of excellent QoL features.

3. Slay the Spire - Spire has ruined all other roguelikes for me. What I love about Spire is that it does not let you get away with just looking for one powerful synergy that will carry you, many enemies are designed to hard counter one-trick decks. You're forced to adapt and actively consider what threats are coming up and what you need to deal with those threats, recognizing the difference between the cards you want and the cards you truly need.

• Portal 2
• Persona 4 Golden
• Galaga

Honorable mentions:

• Titanfall 2
• Destiny/Destiny2 (sometimes)
• Baldies Gate 3

Forever stuck in mid to late 90s JRPGs, if I had to pick 3

Final Fantasy VI Final Fantasy Tactics Suikoden II

Civilization (the OG dos version)

Planetside 2

Warframe

I'll cheat because picking just 3 is impossible.

1. Nethack / Alundra (PS1) / Sim City 2000 / Transport Tycoon Deluxe / Prey / Doom 2016 / Elite / Dwarf Fortress / Rimworld / International Karate / Paradroid

2. System Shock / Ultima 3-8 / Alpha Centauri / GTA5 / Titanfall 2 / Control / Eye of the Beholder / Sensible Soccer / Star Control 2 / Total Annihilation / Impossible Mission

3. Undertale / Bioshock Infinite / S.O.M.A. / Nemesis the Warlock (entirely because of the title song) / Pirates! / Stardew Valley / Revenge of the Mutant Camels

For me it’s always about how much fun I had playing them, so right now and in no order:

• Halo 2
• Starcraft
• Red Dead Redemption

Honorable Mentions:

• Super Mario World
• Super Metroid
• Ocarina of Time
• Fallout: NV
• Assassins Creed: Black Flag
• Deep Rock Galactic
• Hades
• Hollow Knight

• Quake
• Minecraft
• Fallout

• Mindustry, it's open source as well, must have sunk close on a thousand hours into it. Incredible Game, has a good modding scene as well.
• Trove, the opposite of Mindustry, in that the game sucks, I do not recommend. However the game had so much potential and it sort of half realized it before becoming a cash grab. Does a good job of releasing LOADS of dopamine for very simple game play. That said I am now looking into Veloren - which appears to try and be a better version of trove, although taking voxel MMORPG in a new direction. It's also open source so, yeah.
• Minecraft - with mods. Nothing quite beats tech mod mania. I hope some day luanti gets to be a real competitor on some level, but till then.

Disco Elysium

Hi-Fi Rush

...third is hard. Maybe Mass Effect Trilogy. Maybe Rogue Trader/Pathfinder WOTR.

1. Portal 2
2. Hollow Knight
3. Minecraft

1. GTA San Andrays
2. Halo 3
3. AOE 2

These games are rooted in my childhood and connected to memories of simpler times and good friends. I Still play video games but I don't think I could ever experience the same level of joy and excitement that I got from gaming as I did when I was younger. These days I'd rather just go for a nice walk with my dog like the boring old man that I am.

• Diablo II
• Chrono Trigger
• Halo 3

I don't get to play games much nowadays but I was a rank 50 lone wolf back in the day. Good times.

Elden Ring, Dwarf Fortress, and Disco Elysium.

Only 3 choices makes it a tough one since there are many exceptional games...

If I had to erase every experience of all games, the ones I'd keep are (in no particular order): Cyberpunk 2077 Fallout: New Vegas Sunset Overdrive

• Left 4 Dead 2 - for the awesome vs teamplay
• The Last of Us (remake) 1+2 - stunningly gorgeous, emotional heavy hitter
• Disco Elysium - art, literature, as a game

edit: I forgot Guitar Hero / Clone Hero was a game not a 'standard hobby', I play e-drums on that daily still..

Morrowind
Final Fantasy X
The Last of Us

The first two are interchangeable first and second.

Next two are Final Fantasy VIII and inFamous 2, again interchangeable.

Really hard to narrow it down, but I think this would be it:

1. Elden Ring. Before the DLC this would’ve been a toss up for where on the list to put it, but SotE made me confidently place it as my favourite game of all time. I’ll avoid any other Souls games in this list for the sake of diversity but Dark Souls 1 & 3 and Sekiro were all in contention for first place before the DLC. They’d make up spots 2-4 on my list, but I’ll omit them for this one. Elden Ring renewed my love of video games, at a time where I was getting a bit burnt out from playing them. When the DLC came out I played it day one, which I never do for anything, and it completely blew me away, even more so than the base game. The world design of SotE is incredible, the views are breathtaking, and the bosses are the best in the whole series. I cannot fully express just how much I love this game when you take into account the DLC. I’m not sure anything will ever take its place on the throne, but then again I would’ve said the same of Skyrim before I played any Souls games, so only time will tell.
2. Skyrim. Probably a boring or predictable choice, but with over 5k hours it’s kinda hard to not include it. I’d probably add Oblivion immediately after this one, but again, I want to make the list interesting so I’ll avoid it here. Skyrim also helped me through the darkest point in my life, so I’ll always hold the game close to my heart, even if new games come along to displace it on my list. I’ve spent so much time modding this game, and it’s one of the things that first brought me and my wife together when we started dating. It might not be my top spot anymore, but it definitely had the biggest impact on my life.
3. Hitman: World of Assassination. This spot was hard to fill honestly. When I think of my favourite games, I usually just think of the Souls series and Skyrim/Oblivion. There’s lots more games I love, but the top spots are all well above the rest. It’s kind of like movies. I have four movies I absolutely adore, and they’re on the highest pedestal. There’s lots more movies I love too, but they don’t compare. Ask me for my top four, that’s an easy answer. Top five? Near impossible. Same deal here, so I just went with playtime and Hitman is my highest remaining game at around 1500 ish hours. It feels weird to call it my third favourite game ever (or I guess seventh because of the other games I’m omitting from this list but you get the point), but so does any other game I considered for here, so I’ll include some honourable mentions below. But back to this game, I feel Hitman is the perfect game for what it is. It can be serious for sure, you’re a hitman taking on contracts, but it can also be completely ridiculous too. One minute you’re tinkering with a race car to make it violently explode on the track to kill your target without anyone suspecting foul play, the next minute you’re dressed as a flamingo exiting the mission by literally flapping your wings and flying from a helipad. 47’s permanent seriousness in the most ludicrous scenarios is peak comedy honestly. Going to a high society Parisian fashion show dressed as a children’s clown and punching out the CEO is a totally normal thing you can do in this game, it’s amazing. And if you don’t like that vibe, you can be a total badass and do a full blown shootout, or a stealthy assassin and eliminate your targets from the shadows with none the wiser. It’s the ultimate hitman/assassin sandbox game.

Honourable mentions: Portal 1 & 2, Pokémon SoulSilver, Hollow Knight, Dishonored, Red Dead Redemption 1 & 2, Batman Arkham Asylum and City, Inside, Gunpoint, any Forza game before the most recent one (haven’t played it), all the Bungie Halo games, and many more. I just love video games I think.

Ragnarok Online in the early 00s is the only reason I’m alive to post this comment

Diablo II for sure, what an amazing technical achievement in the year 1999

Theeeen probably Earthbound.
