Diablo 2&3
LoZ OoT & MM
Marvel Heroes 2016
Fallout NV

Skyrim. Between the original version and SE, Ive dumped around 900 hours into it
Banished
Fallout series. Pretty much every Fallout game can suck my soul away for days, especially 3

Bomberman (NES)
Stardew Valley
Minesweeper
Bejeweled
LYNE

Final Fantasy games, Legend of the dragoons, Chrono Triger and Cross...

I used to play Morrowind a lot, now Total War Rome II & Attila, Path of Exile, Diablo III...

Final Fantasy 15
Bloodborne

Jill and Stella best waifus 12/10

Age of Empires II
Deus Ex 1

Baldur's Gate II used to be in this club, but I feel I have sunk enough hours in it in the past nearly two decades.
Same goes for Fallout: New Vegas, although I may re-visit that game eventually.

Binding of Issac for sure

Pinball

Skyrim

Deus Ex Human Revolution, Far Cry 3, League of Legends.

LucasArts' Gladius

Fire Emblem Awakening
Mario Party 7
Pikmin/Pikmin 2

Sid Meier's Pirates, Mount&Blade and Diablo II.
They have a warm and cozy feeling surrounding them,
even to this day, after at least 4-5 -playthroughs each.
Thanks for the GA as well (almost forgot) :D

Isaac, Dragon Age Origins and original Most Wanted.

UFO: Enemy Unknown

Fire Emblem franchise, Civilization franchise, Roller Coaster Tycoon franchise(+Planet Coaster) and Recettear for me

Mount & Blade: Warband and Crusader Kings II are games with great replayability, and though I'll occasionally tire of them, after a bit of a break I'll go back and have even more fun than I had before.

Although as a narrative-based game it lacks the same degree of replayability, I've still played through the visual novel Analogue: A Hate Story multiple times, and still can't get over just how good it is. It's a real pity the sequel was such a let-down.

Starcraft II, Dark Messiah of Might & Magic

Dota ofc

Torchlight
Morrowind & Skyrim
Hyrule Warriors
Link Between Worlds
Fallout New Vegas
Resident Evil 4
And a resent contender, Valdis Story: Abyssal City

Fallouts 1 & 2
Zombies ate my neighbours and star fox (snes) [probably more, but these were the only ones i never got tired of]
Mount & Blade
Volgarr- i get tired of it then come back then get tired then...
Subnautica
Stalker
Tomb Raider
Serious Sam(s)
(Old) Team Fortress 2
Portal
Master Spy (it always amaze me, idn why)
Hotline Miami
Age of Wonders (older ones)
Overlord 1 & 2
Dead Cells is a good candidate
...
