ShadowMan from 1999. That's one of the (if not the) first narrative action adventure games I ever played and a big part of my childhood. The mixture of blood, gore, creepy music and enemies and great setpieces (you play as the walker between the worlds of the dead and the living and can switch between them) fascinates me to this day. When I was a child, it gave me quite a few nightmares, but I still finished it. It's an absolute masterpiece.

NightDive recently remastered it and it's even better now.

ARSENAL Extended Power. An old strategy game from the early 2000s. Still fire it up once a year to mess around.

Gothic 1 and 2 (from 2001 and 2002 respectively) are still some of the best games I ever played. There is also a very active modding community, and some mods are even much better than the original game.

@TheReanuKeeves Doom

I go back to play some nethack pretty regularly.

I still play WoW. That's a 21 year old game.

(The housing is so much fun!!)

Playing regularly? Minecraft.

There are a few games I revisit as my kid grows up and gets to experience them for the first time, but Minecraft keeps coming back.

I've been replaying Tenkaichi 2 lately

Arcanum from Troika and Fallout 1&2 for me

I still play NES games often. These were the games of my childhood. Balloon Fight and the original arcade Mario Bros. are always fun for shorter sessions. And I still enjoy playing through Super Mario Bros. on occasion. I very rarely have ventured into games older than the NES.

Started playing Spelunky HD again the other day, the sequel is better but the original is still fun to revisit.

Morrowind and Fallout: New Vegas sometimes. I've tried playing the original two Fallout games but I keep bouncing off the first hour or two.

Some Guilty Gear XX AC+R with a friend -- we would love to play some old Tekken games too but we're both on PC so Tekken 7 is the oldest available.

Every once in a while I'll play some Sacrifice, such an amazing game that's dying for a remaster.

Technically Team Fortress 2. Though not often.

I'm playing through Final Fantasy 2 right now but the pixel remaster version which came out in 2021 which is why I say technically.

The original Bard's Tale trilogy. I just finished I a few months ago and have been working away on the Destiny Knight.

It's so cool to be able to port your party over from the prior games and keep building!

Mario 64 on original hardware. Never did finish it as a kid so no time better than the present

Battle for Atlantis

Thief: Gold

The Dark Mod scratches that itch very well most of the time, but the OG had better story telling across multiple missions

MechWarrior 2: 31st Century Combat (1995)

Before I got a Switch, my last Nintendo Console was a Super Nintendo and missed out on Wii/Gamecube/WiiU, family was a Playstation family lol, so now Im going back and playing all the Zelda's!

Portal. It's older than you think, but still solid.

I recently picked up Diablo 2 again, that and Doom which I play off and on. I really need to find a copy of Wolfenstein now that I'm thinking about old games.

About once a year or so I go replay Morrowind, the chaddest of the Elder Scrolls series.

This past year I replayed Morrowind with Tamriel Rebuilt tacked onto it, which has been extremely cool and fresh. TR really feels like official content a lot of the time, it's quite good and the love that's been put into it is very apparent.

Super Smash Bros Melee (2001)

Portal (2007)

Red Dead Redemption (2010)

Portal 2 (2011)

Journey (2012)

Tomodachi Life (2013)

Gothic

The barcade near me has a Sinistar (1982) cabinet and I play it every time I go. I’m not even that good at it, but I love it so much.

Also I love those Lucasarts point and click adventure games. Grew up playing Monkey Island and play it again every once in a while.

River Raid, Atari game from early 80s. Play it on analogue pocket currently

I'm on a retro game kick lately. I am currently playing Pokemon Leaf Green and Chrono Trigger (for a fiesta event) and will likely move on to Castlevania: Symphony of the Night afterward.

DigDug on MAME

Diablo 1 (it runs really well with the devilutionx engine reimplementation)

I play retro games I missed growing up so I’ll soon be starting final fantasy 6

Last three were Star Ocean (the first one), Radiata Stories, and Skies of Arcadia.

Currently playing Alundra because a friend grew up with it and wanted me to play it. Honestly it's not great but RetroAchevements made the bosses extraordinarily painful to master, which is uh ... fun. Yes. Fun, let's go with that.

Oh and ps these commenters all have fantastic tastes.
