What's your most played game?

Guild Wars 2. I have played it for 850 hours. I adore it very much and it's probably my favorite game of all time.

https://www.steamgifts.com/discussion/3YpN0/what-is-your-most-played-game-on-steam/search?page=8 not pretty dead but bumpable, my answer is almost still the same, an Idle game.

Now, something different taking out "free games", comes dishonored2 with 88h and not yet 100% achievements, but both low and high + stealth/ no killing runs done. Will do the no powers run next month or so.

of all times, by far Ultima Online

dota 2 , 1k hour+ but i quit 2 year ago

My most played game of all time is easily Everquest 2, with thousands of hours, though Asheron's Call might be a very close second.
My most played Steam game is Borderlands 2 at 934 hours.

World of Warcraft. For most people, it's measured in days and not hours.

Stellaris, 741 hours... Paradox own my soul

Non-Steam game Command and Conquer Renegade online 10,000+ hours. In-game moderator and Server Admin since 2005.
Steam Borderlands 2 1000+ hours

WarFrame 906 hours, those are the Steam hours btw. I played a bit before it even got on Steam (CBT and OBT).

ARK: Survival Evolved
4,193 hrs on record

roller coaster tycoon 2 triple thrill expansion pack!!!!!!!!!!! best 10$ ive ever spent, i think i got it at a costco or somthing

Skyrim, 112 hrs on record.

I find it hard getting past the 100 hour mark with most games. I usually just play until the main objective is complete, then move on the the next game.

The Binding of Isaac: Reirth - 1005 h.

GTA V 3141H

Dota 2 - 10100 hrs.

Non Steam: Trackmania United Forever 10k+ hours, Steam: TF2 ~800 hours

On Steam, it is New Vegas with 800 logged and +150 unlogged hours.
In general, Baldur's Gate II and Age of Empires II, both are somewhere over 2000 hours.

Killing Floor 2 - 405 hrs on record

Path of Exile over 2k hours.
Before that it must have been Diablo 2 with thousands, too.

Minion Masters 500h+

My most played Steam game ever is Warframe with 557 hours, which I started playing when open Beta began and I stopped playing sometime after it launched on PS4.
My most played current game is Rocket League.
Since you played a lot of Gmod, ever play the standalone Tower Unite? I've enjoyed that since it was in a Humble Monthly.
