Diablo II Resurrected. I've been playing it (Diablo II) for 20 years now. Even though I know the game inside out, a new rare rune drop can still make my day. I usually listen to podcasts meanwhile.

Vampire Survivors was tons of fun until I unlocked pretty much everything, but it also goes great with podcasts.

Clone Hero. Even though I only have a keyboard (so say goodbye to the fast strum bits), It often takes me from 'I just want to chill' to 'this song was FIRE'.

Diablo 4. I usually turn on Futurama when I play.

Stardew Valley, Animal Crossing, My Time at Portia, Cozy Grove or Good Pizza, Great Pizza!

Bloons td6 is pretty cool and laid back.

Stacklands, inscription, forza.

Stacklands was surprisingly addicting

Inscription was fun and challenging but not too crazy if you get creative ;)

Forza - I mean really any game where I can drive around. Fun to try to hit some corners sharp or do some tricks in gta.

Spend hours downloading / messing with proton / configuring, and then play for 15 minutes...

At this point I'm almost convinced I just like the setup process.

Otherwise probably quake.

Not a long or super replayable game like some of these answers but Jusant is super chill.

I have several games for a lazy evening on the sofa, so it depends on the mood.

I hoard virtual cars, tanks and ships, so I pick CSR2 when I want to do an event there (daily boring grinding tasks are automated). When I want to shoot I either junp in World of Tanks Blitz or World of Warships Blitz.

When in a mood where I want to just tap around, I dust off Hay Day.

Gershwin Impact has been on the tablet, but after a few attempts to play it, it's removed again. Looks nice, but not my style, yet.

So what games do you play when you just wanna relax?

Solitaire

I usually listen to music and play driving games like Forza Horizon, BeamNG, or Dirt.

Also roguelike games like Deadly Days.

BeamNG

Car/truck driving simulator with the best crash physics you'll ever see. Great to just drive, off-rod, modify cars, race or just smash cars up. The game is only limited by your imagination.

You want arcade experiences

I play Tibia. It's an old 2d MMORPG with endless grinding. Loads of quests and a playerbase where the average age is like 28.

For me, it is Nova Drift. It has been the game I go to when I just want to relax and chill.

Sometimes I feel like I'm the only person on here who plays Hollow Knight. When I want to chill, I like to start a new game and just go through the early-mid game exploration phase. No pressure, skip bosses if I feel like it. Just run around and enjoy the atmosphere and music. Love it.

Honestly, some visual novels like Ace attorney, Katawa shoujo, Steins Gate, Clannad are very chill.

Genshin Impact has been my comfort game the last 2 years

Pokemon Fire Red or Dark Souls

C&C Generals World Builder. I just make maps while I'm in discord.

It's stimulating enough that it keeps my mind from wandering from a conversation, but brainless enough to be engaged in the conversation.

I'm also partial to Minecraft. Just decorate a little section then log off until tomorrow
