What Steam game have you the highest playing time?

Dragon Age, Mass Effect 1-2-3, Star Wars The Knights of the Old Republic and CS 1.6

537 hours in Team Fortress 2, and 504 hours in Garry's Mod. :)

I've also played Saints Row 3 for 285 hours, Portal 2 for 101 hours, Counter Strike: Global Offensive for 85 hours, and The Elder Scrolls V for 80 hours. :D

Sadly Dota 2, I dunno why I played it so much but Binding of Isaac rightfully takes 2nd place.

Terraria, at 178 hrs. And then I lost my character, and world, and I haven't played it since, lol!

RIFT - 108 hours, darn i love that game but i got bored :/
P.S.: It's F2P

These are my top 5.

Terraria--291 hours
Blood Bowl: Chaos Edition--244 hours
Borderlands--236 hours
The Binding of Isaac--224 hours
Madballs in...Babo: Invasion--55 hours

BioShock: Infinite - 56 hours
Borderlands - 55 hours
Red Faction: Guerrilla - 55 hours
Dead Island - 53 hours
Doom 3: BFG Edition - 52 hours

I don't play multiplayer so that's probably why my times are not very high.

f-ing dota..1350ish... apart from that unepic - 24 hours.

1. Crusader Kings II
2. The Witcher
3. Empire: Total War
4. Civilization V
5. COD 4

Killing Floor - 421 Hours

(I've had this game for 4 months)

Garry's Mod, first game I owned on steam that wasn't F2P, 472 hrs

well mine most is black ops and call of dyty modern warfare 1200 hours combined.After that year began exams for univercity and dont play too much my games

Team Fortress 2 - 427 hrs

One of my first Steam games. Don't play it anymore.

Fallen Earth 220 hours, Used to be a Game Helper/gm

COD: MW3(+300 hrs), hawken(+110 hrs) and sanctum 1&2 (+100 hrs both, 50 on each)

Europa Universalis 4 on steam though likely skyrim or morrowind overall.

I'm pretty sure I should be substracting some hours on everything, I do tend to leave my game running when I go afk for any period of time.

1. Stronghold Kingdoms - 1,258 hrs on record. I was pretty surprised, considering I just checked in once or twice a day to do like 10 min stuff and then go back to surfing the internet. Although I never did log out or closed it off now that I think about it. This was also the only game I played on my pc because it couldn't handle anything else and I was too lazy to upgrade. Also I mostly played nds games in this period.

2. FINAL FANTASY VII - 124 hrs. Lot's of grinding, seriously all I seem to remember off this game is Chocobo's, spamming KoTR (highest summon with a minute long animation),and grinding. Also Sephiroth was there somewhere at the end. I did collect and leveled up everything though.

3. Path of Exile - 105 hrs. I did like this game a lot. Also lot's of grinding for achievments I failed anyway :/

4. Dragon Age: Origins - Ultimate Edition - 79 hrs. Still not done...

5.Team Fortress 2 - 77 hrs. 20 of which I spend this week just idling.

Yeah I idle too much.

My top 10:

Team Fortress 2 - 1323 h - At least 800 hours of playing, the rest is trading, idling and rendering.
Blacklight: Retribution - 492 h - Possibly over 600 hours because I played it without running Steam.
Killing Floor - 384 h - Finished most maps on hell on Earth except for the newest ones.
Left 4 Dead 2 - 342 h - My first multiplayer game on Steam.
Call Of Duty: Black Ops 2 - 311 h - Last played multiplayer game.
Natural Selection 2 - 139 h - Great potential, but bleeding players rapidly.
Terraria - 132 h - Collected/crafted all the best items in the game.
Alien Swarm - 99 h - Only 1 campaign and still so much fun.
FTL: Faster Than Light - 87 h - Currently playing.
Borderlands - 60 h - Finished everything but Crawmerax.

My highest is killing floor with 174hrs

Call of Duty 4 over 2000 hours

Apparently I've played 111 hours of La Mulana. My guess is that at some point it didn't close down properly and kept racking up play time, because I've played it MAYBE an hour.

After that it's 98 hours of Team Fortress 2 (Prop Hunt. I can't play 'real' TF2 to save my life, but I enjoyed Prop Hunt. Actually never idled that I can remember), 48 hours of Starbound, 45 hours of Rift, 35 hours of Terraria and 29 hours of Don't Starve.

Path of Exile would also probably be up there, but I downloaded and played it before it got on Steam and haven't bothered to set it up for Steam yet.

• Torchlight - 35 hours
• Jamestown 18.2 hours
• Half-Life 2 14.1 hours
• Super Sanctum TD 10.9 hours
• Defense Grid: The Awakening 10.3 hours
• Plants vs. Zombies: Game of the Year 7.7 hours

These are my top 5:

• Counter-Strike: Source - 1122 hours (played it hundred of hours on a cs_office rush Server, loved the Custom Maps and of course competitive 5vs5 with friends)
• Dota 2 - 447 hours (I really love that game, but the Community is horrible.. so I haven't been playing it for a while now)
• Counter-Strike: Global Offensive - 215 hours and counting (a decent remake, not the best but still a great game for competitive 5vs5, oh and I like the Phoenix Maps)
• Worms Reloaded - 136 hours (perfekt Remake)
• Worms Clan Wars - 97 hours and counting (the best 2D Worms game which you can buy right now.. small player base but good game). :)
