Space Station 14.

This is a remake of SS13, and it's an open-source labor of love. Sessions are ~45 minutes to 1½ hours. Complexity is daunting, but just don't go in expecting to be useful - expect to be a passenger, drink beers, and possibly get killed or rescued, maybe have some RP or semi-RP chats.

But you'll learn, and slowly, how things work. Maybe you can be an engineer intern and fail horribly while everyone depends on you. Maybe you can be in security and get killed. ..and maybe, just maybe, someday you'll win, and know you helped to make that happen.

Duelyst II is a fan revival of essentially a Hearthstone clone played on a chess board. It's still in it's early stages, but it's fun and promising.

Muck is a roguelike survival. It's got kind of a silly TWAB vibe. It's fun to play with friends but you don't have to.

TF2 is a casual FPS, as you probably know. It still holds up. I'd recommend playing on custom servers.

Emu🦢lation.

Great roguelike "Shattered Pixel Dungeon"

This is a free (as in freedom) game, I've done dozens of runs, there was enough depth and graphics are pixel art. Available for computers, phones, whatever

My friends are enjoying mmorpg Trove (steam)

Someone else said Vampire Survivors, the game I like a lot recently is 20 Minutes Until Dawn. Lots of guns, upgrades, and characters to have fun with.

Tibia is a german old school mmorpg that just refuses to die. I had loads of fun with it back in the day.

I'm so bored with all the AAA's and big games. So, I would suggest Guacamelee, if you are seeing this then you should know both parts of the game are currently free on epic games.

I like Hades, Vampire Survivors, Fresh Woman (NSFW), Noita, Brotato, Yi Xian, SEUM, Factorio, Rim World, Oxygen Not Included, SNKRX, Blasphemous (if you are patient), Stacklands, Hollow Knight, Card Hog, Slay the Spire, Dorfromantik, Super Mega Zero, Geometry Dash (lol), Terraria (Must Play), Raft, Satisfactory (don't think low end pc's can run it, not really sure).

Everyone of these are chill games except Blasphemous. I'm chill games lover, so so done with all the hyper dopamine AAA titles. I don't like to waste my time on games so I go for the games which give me more in less time. I play valorant sometimes but only one or maybe two matches per day. I play clash mini, vampire survivors, sonic forces, Windows XP Space Cadet (available on github) on android.
