what is the best game(s) you won on steam gifts

For me is The Dark Pictures Anthology:House of Ashes

Rise of the Tomb Raider

off the top of my head, Detroit become human
never would have played it if i didnt win it
i mostly win hot garbage ¯_(ツ)_/¯
always try to play my wins the 1st few days of getting them

winning Monster Hunter: World resulted in 600 hours of playtime and 100% achievements 🙃

Hm, difficult to say. Looking through my wins a few would be viable for the best. Maybe Nier: Automata.

My favorite wins so far have been Astronarch and Space Crew - Legendary Edition

Kitty Powers' Matchmaker. Gotta love matching those makers.

Deep Rock Galactic

Baldurs Gate 3 :3

Torchlight. I really enjoyed that one

Red Dead Redemption 2

minе is doom 64

Probably Red Dead Redemption 2... probably, because I was not really able to play it, which I feel really bad about, especially because it was a direct gift from Steam. Though it does run on my PC, the fps is so low at times, that it doesn't make sense to play it :( .
For the past 2 years I am about getting a new comp, but firstly I did have some serious financial problems and for the past 7 months, while I could afford a decent PC, I'm planning some drastic changes in my lifestyle and I'm just not sure, if I will still need my main comp to be a laptop or if a desktop will serve me better, so it's still on hold.

Pillars of Eternity 2: Deadfire and Baldur's Gate 3 (both are among my all-time favourite games).

Can I do a 3-way tie? Out of my SG wins I finished, I enjoyed the most:

1. Hollow Knight
2. The Vanishing of Ethan Carter
3. Unavowed

Stronghold Crusader

I know you asked for the best game, but I'm thorn between three:
The Elder Scrolls V - Skyrim (2011)
Oxygen Not Included (2019)
Dyson Sphere Program (2021)

Skyrim holds a special sweet-n-sour place in that list because I won it from Xxxka and I commited to play it. I really, really wanted that game and I thought I was going to play it... But as some of you know, I've had a bad time with trying to play games (or watching movies, listening to music, reading books) in the last years, so I ended playing it "tomorrow", which never came, and I was rightfully blacklisted by Xxxka. I still intend to play it and it's in the top spot of RPGs I intend to play now that it seems I'm back at gaming for real. (5 hours a day is my average in the last 2 months). However getting into an RPG is not like racing. FH4 for me is a casual game that doesn't strain too much my poor overmedicated head. I usually get into RPGs too much and become obsessed once I get the grip of the game.

Oxygen and Dyson were from the same person, S4k1s, to who I'm immensely grateful because these games were in my most wanted list like Rimworld or Automobilista 2 Season Pass. It is hard to choose between both, as they're not the same yet scratch greatly that itch of "ok, one more thing to do and I stop for today". However I think once I get tired of racing I'll go through Oxygen Not Included.

thanks for skyrim - 918 hours

Terraria - 257 hours

BRATTAHS privileges

i won some really good games like Hunt: Showdown and fallout 76 but the best one imo is Batman: Arkham Knight Premium Edition

Ryse Sons of Rome for sure.

I will answer in few years:)

I would like to give out three awards to games that I would count as my best wins.
Highest production quality: Ghostrunner
Longest playtime: Slay the Spire
Most fun I had: Inscryption

Can i give more than one? :o
Here is my top 3:
Tales of vesperia
Crosscode
The wolf among us

For me it's either gotta be the Just Cause Collection (which was JC1, JC2 plus DLCs for both) or the Life is Strange Complete Season. Won both in early 2016 and had a ton of fun playing them.

If I can only pick one I guess I'll go with Sunset Overdrive, mostly because I probably wouldn't have played it otherwise and absolutely loved it.
Honorable mention goes for Mirror's Edge since it's one of my favorite games of all time, but it didn't feel right to pick that one because I had previously played it at a friend's house before winning it here.
