Monster Hunter World. I usually stop playing games after I roll the credits, but I have been addicted to min/maxing in that series since Tri.

Terraria

R6: Siege at 1800, followed by Terraria at 1100. Terraria is the better game of the two.

Minecraft, Factorio, Satisfactory and Dyson Sphere program have the most real playtime, but idle games have the top slots.

Craft the world, Valorant and AoE3

World of Warcraft - over 11k hrs

Guild Wars 2 - over 5k hrs

Warframe - 2200 hrs

Minecraft - who knows… a lot

Warframe, by a big margin.

Team Fortress 2 easily. Been playing since 2008. It scratches an itch that no other game can scratch. Ironically though, my second favorite fps game is also TF2 (Titan fall 2)

Factorio.

I’m approaching a thousand hours in Elite Dangerous. Quoting myself from a week or two ago:

It’s different to most other games, by not being goal-oriented except for the goals you set for yourself. No main quest line dictating progress. No mandatory tasks. No win condition. Instead, it drops you into a simulation of our entire galaxy roughly 1300 years in the future, where humanity has mastered hyperspace travel and spread through hundreds of star systems.

(To give an idea of the simulation’s scope: Around 85 million systems have been recorded by players so far, and those are a vanishingly small fraction of what’s out there. Space is big.)

I like that it offers a variety of activities to fit whatever mood I might be in on a given day. I can hunt pirates, mine asteroids, engage in a bit of piracy myself, find and collect bio samples, infiltrate rival settlements, venture into vast unexplored areas of space, discover Earth-like worlds that nobody has ever encountered before, defend humanity against hostile forces, photograph beautiful stellar phenomena, rescue stranded survivors, customize and finely tune my ship to perform beyond its original specs, team up with friends, pledge to a political power and expand their influence, or chill out as a space trucker and haul cargo to earn enough money for my next upgrade. It can occupy all my attention, or just be relaxing entertainment while I listen to music or an audiobook.

It’s an MMO in the sense of having a large game world (galaxy) shared by all players in real time, but PvP is optional. One mode exposes you to other players, while another limits you to NPC encounters. You can switch between them at will.

One warning: A space ship has more than a few controls to learn, and they’re better suited to a game controller or HOTAS than a keyboard and mouse. I use button combinations for almost everything beyond basic flight controls, since there aren’t enough buttons on a controller for everything.

It’s either the Sims or Animal Crossing.

I have a lot of hours of Morrowind and Doom 1&2, as well as Warcraft 2 and Ultima Online, but I dunno the hour count

WoW, Grim Dawn, Don’t Starve (Together), Stardew Valley, Terraria, Skyrim, Borderlands

Minecraft, and the number is still growing.

STALKER and The Elder Scrolls probably hold the record. I may have wasted even more time in my life on World of Warcraft, but I feel like that doesn’t count since you’re just in a fucking trance for several years until you finally break away.
