What's your most played SG win?

Apparently it's been Contagion - I had to look up my stats.

Tap Heroes with 70+ hours on it
That is not idling, that is IRL play time tapping.

Rocket League - I still can't believe I really won it. :-)

Thanks for the awesome giveaways!

Most played game that I've won... maybe SOMA, about 22 hours.

I'm working my way through my backlog, trying to finish the game if I enjoy it.
So far I've completed SOMA, 12 is better than 6, D4 Dark Dreams Don't Die, The Forest of Doom, Life Is Strange ep1,

This is actually a really good question.

XCOM: Enemy Unknown. 66 hours.

Although 10-30 of the hours I did later after getting XOM EW.

Currently BL. My most played SG win is Saints Row 4. I don't remember if I wishlisted it or not but I did want to play it.

To The Moon!

I'm surprised to say but Call of Duty: Black Ops zombie mode

Stupid stats now I see that I don't have enough time to all my games :( but I will not stop trying :P

I think mine is South Park: The Stick of Truth at 13 hrs.

it came from space and ate our brains. haha don't judge me, I'm in love how much fun simple games on steam can provide.

The Elder Scrolls Skyrim for me, with 55 hours played and still playing.

Giana Sisters: Twisted Dreams at 9.5 hours. I've gotten stuck at one stage and have given up on it for now.

Mad Max with 49 hrs completed 100%. Followed by Transistor which I won from you :D with 13 hours. I loved the game so much that I played it again right after finishing it for the first time. Managed to complete 98%.

Deus Ex: Human Revolution = 31 hour

Don't Starve with 100.6 hours

Does it count if I won DLC for a game I play a lot. Case in Point I won Dragonborn (just need Dawnguard now) for Skyrim which off Steam I've put quite a bit of time into it, but online I put 9 hours in the game.

If not then Borderlands TPS is it for 6 hours.

Leviathan: The Last Day of the Decade with 14.5 hours and A Vampyre Story with 14.2 hours.

Most time i've spend on game from steamgifts was for a game called One Way Heroics which was far better then i've anticipated. 43h of gameplay and i've beaten it previously on drm so it's even longer then that. Next place is for game i had wishlisted for some time and even i gave away one copy of it. Batman: Arkham Origins. I've won in giveaway for it and then won second time for season pass for it so... 39h. Yes. It was quite good.

Sid Meier's Civilization V - 17 h.

Really good question, as I still haven't started big on the timesink ones , so it's surely will increase.
Currently Magicka 2 with 43 hours, followed up by Victor Vran's 27 :3

Mine is 'ancient planet' with 22h. I won some really nice games but I have the "omg, if I begin this game I will sink so much time in it" syndrom. I should change this and play the games that really interest me...

Looks like Kingdom Rush, 25 hours!

The Witcher 3: Wild Hunt, 210 hous so far, and I plan a few replay in the (near) future.
