I've got over a thousand in Space Engineers, although some of that is from leaving it on overnight to refine materials. Or possibly exiting the game, but forgetting to actually leave the main menu. Does Steam track time when the computer is asleep?

But I've likely got close to ten times that number in Dwarf Fortress. I've been playing it off and on for close to a decade and a half now, and when I get into it whole days can just fly by.

Probably Diablo 2 back in the day. No idea how much hours were sunk into that.

I must prelude my statement with two facts of life: I was meant to be an MMO player, and controller is my way of doing it (yes, I know K+M is technically better, bite me)

That out of the way, 3667 hours in FFXIV

CK2 - 400h

Fallout NV (guessing most of this has been TTW) - 190h

Stellaris - 180h

Xcom 2 - 140h

GTA 5 - 99h

Cities Skylines - 95h

Skyrim - 90h

Civ5 - 85h

Xcom - 83h

The other games I've played are pretty much the standard play-through times. (< 70h)

Path of Exile - 1000+ hours

350 hours in FH5

I wish I could filter out idle and clicker games. My biggies are Factorio and KSP for non-idle games. Several thousand hours in each.

For me it's 7 Days to Die, at 1580 hrs.

I've played a little bit of Warframe...

I have over 400 hours on Rust which is just 6 months after playing the first time. But there are players with over 10,000 hours in this game.

Can't access my time spent right now, but between Warframe and idle/incremental games, THOUSANDS of hours.

Does that count as cheating?

Well, I seem to like first-person shooters:

but realistically, I have like, many dozens of games with like 30-80 hours played, I'm really into variety gaming.

The only exceptions to this are RuneScape (OSRS and RS2 back in the day), World of Warcraft (I played a ton of Cata until maybe a year before Legion), Starcraft 2, League of Legends, and Osu.

LIVE FREE IN THE NC

I’ve spent a lot of time on the XCOM games. Installed 2 recently and having almost as much fun as the first time (this is like the 10th).

I’ve tried Risk of Rain 2 a few times. Like the comment I left about Rim World below, it just doesn’t click with me and I love shooters. Wondering what I’m missing that everyone else sees.

Your mother (and I) play Counter-Strike 1.6

Hearts of Iron 4 at 1200 hours, Crusader Kings 2 at 1000 hours, Terraria at 600, Team Fortress 2 at 300 hours.

Also Rimworld should be somewhere at the 500 mark, but a lot of my hours weren't recorded on Steam (I have bought the game now though).

Minecraft and some of the Touhou games (I haven't been keeping up with the newer ones). I don't have those getting time tracked on Steam. Stardew Valley is the next most-played, and my highest played on Steam.

I also sank SO MUCH time into Nintendogs as a kid I think it is worth a mention.

If idle games count, PokéClicker.

4000hrs in Dayz. No game like Dayz has ever been able to give me the same adrenaline rush, it's just so intense.

Dota, 9,000+ hours. I don't play it anymore though, toxic af

I now mostly play Path of Exile and World of Warships

I used to have about 4000 hours logged in tf2 and counter strike source, but they dropped thier playtime database at some point since then 😅 so now my top one is rocket league at around 600 hours

Blockland... played a lot, for years. Before Minecraft, before it came to steam. It turned me onto Tribes.

The Long Dark, I start a new sandbox every winter. 650+ hrs. I have other games I played for much longer but haven’t played them lately.
