Games that I had, wanted but never got, or just missed growing up. It's like a nostalgic topiary. I find hunting, testing, and playing very relaxing.

Walking simulators and story/emotion heavy games like Life is Strange. Sometimes a good feels helps.

And Skyrim is my comfort game. Helps with panic attacks.

Diablo 2. I return to it about twice a year and have a good time starting a fresh playthrough farming gear for a few different builds. Especially with the QOL that resurrected has brought.

Tunic for me, simply going, walking around, revisiting a place know well

And "A Short Hike" for my SO, they where feeling bad one day and came to see me. I got Ice Craem, some Blankets, and gave them the controler next while I was against them. Now everytime they felt sad they go on a walk to this mountain. I surprised them preparing their laptop by putting A Short Hike Wallpaper, and made their day like that

Stardew Valley or MechWarrior Online.

Baldurs Gate 1.

HBS's Battletech (2018). One, it brings me back to some good high school memories playing tabletop with my friends, and two, you can never have too much big stompy robots shooting each other.

Any SoulsBorne, Doom (mostly Brutal Doom), PSX Resi's or SOTN. Mostly the total comfort of playing what I know so well for a wile.

League of legends obviously I enjoy the toxicity

Basically anything single-player from BioWare and Bethesda that's not Mass Effect Andromeda.

Battlefield 1. I hop on the same server every time and it's a nice way to calm myself down if I'm stressed about something in real life. It's much more fun to be stressed about staying alive and helping my team the best I can. The game sparked a strong interest in history for me aswell, so it's also a comfort zone in that sense too.

Tetris. Always down for a quick game

Sid Meier's Pirates

I have dozens of thousands of hours logged in that game, all because it's so easy to get in to and so hard to get out of. Just turn it on, do some pirate shit, then realize it's been hours and you probably should have eaten or slept at some point.

Super Mario Bros and Wolfenstein 3D

Remembering simple times, no complexities, pure fun. While chugging coffee and oreo.

Idle games or incremental games are my go-to for casual play. At the moment I'm playing through NGU Idle mainly because It's a super slow burn but unlocks lots of goofy features over time. I've been progressing for a couple years now.

Super Metroid. I replay that every year and I've been doing that since I was 12, I'm now 29. Greatest game ever made. The rest of the metroid series gets replayed at least every other year, absolutely amazing games and there's not much else like em unfortunately.

Don't Starve Together. I suck at it, but I love opening up the map and building up my base.

Older: Command and Conquer Generals. I’ve started playing it with my kid which is fun. Newer: Rocket League. It’s been fun especially when I stop caring about ranking up. It’s just a game and I can play for 10 minutes and walk away.

I have over 500 hours in Particle Fleet: Emergence. Very chill level-based game where you can slowly move forward and beat a map over an hour or so. All the Knuckle Cracker games have tons and tons of user content available so there's no shortage of maps to play.
