Favorite game you've won on sg?

Many. But I'm going to go with "A Hat in Time".

I have so many games that I have not even touched yet but Disco Elysium is very memorable. I only have played a few hours of it but Cuno is hilarious, well the whole game is kind of off in a good way.
As for something I have played thoroughly Symphony of War: The Nephilim Saga was really good for a little indie TBS game. I had fun just building units to poop on the enemy.

Truly a good question.

Skyrim is definitely up there... although most of my hours are on a filthy pirated version(hundreds if not thousands of hours not logged!), that kind of life is a relic of my past.

Hellblade: Senua's Sacrifice is very much up there as well, it did make it to my favorites list.

Ratchet and Clank: Rift Apart, this was my very first venture into the franchise and it was great.

Lies of P, this is the very first true souls like I have beaten, I have touched others and gotten distracted and haven't beaten them yet. Had a great time with it.

Celeste... one of the top precision platformers out there, and has all the assist modes needed so you can beat it(start with none, then pause so you can properly angle your jumps, etc... as needed), also made my favorites list(I technically also own it on switch... but haven't beaten it there yet >>)

Death's Door, more Zelda like action-adventure

Class of '09 and The Cosmic Wheel sisterhood, both visual novels that were great for very different reasons

I guess Hellblade and Celeste win by technicality of making it to the top 20 or w/e list

I'd have to say Yakuza 0, a great game that got me into the Yakuza series which I've really enjoyed.

The favorite? The favorite?? MWA HA HA HA HA.... TIME FOR ANOTHER TOP10, nay, TOP11 LIST!!! Bask in my eternal wisdom!

1. Horizon (Zero Dawn)
2. Hollow Knight
3. Unavowed
4. The Vanishing of Ethan Carter
5. The Witness
6. Tomb Raider
7. Middle-Earth (Shadow of Mordor)
8. Planescape Torment Enhanced Edition
9. Hellblade (Senua's Sacrifice)
10. Okami HD
11. XCom2

(All IMHO. Sorry for shouting.)

Cheers!

Detroit Become Human
never would have played it otherwise

Meanwhile i dont test some which i've won, Bounce ASMR (that became free right after i got it, and actually clutched the giveaway by entering like 1 minute left?)

by sheer time played, definitely the void rains upon her heart, over 222 hours and there will be more later i'm sure. didn't really know what i was getting when i won it, just thought it looked interesting.

other notables are:

• resident evil 7 - maybe my favorite of the series, definitely in the top 3.
• dishonored 2 & prey - i like immersive sims, and arkane knows how to make them.
• fallout 4 - played this a while back shortly after release (not on steam) and was kinda disappointed, but coming back to it years later i actually had a lot of fun with it. also got to play the expansions this time around so there was something new at least.
• stray - cat.
• tunic - another huge surprise where i thought it looked interesting but was way better than i was ready for. unfortunately it doesn't have the replayability of tvruhh.
• haven park - pretty short, but it stands out. very similar to a short hike.

Truly a difficult question, many of my wins have been quite good in their own ways and it's tough to pick a favorite. The answer can depend on my mood as well, and I know I've answered topics like this one before with different answers.

This time I think I'm doing to pick... Borderlands 2
I originally tried the game during a free weekend in 2014 and just shrugged at it. The game was okay but I had no interest in buying it. Still it wasn't bad so whenever I'd see a giveaway for it, I figured why not enter, and three years later I won it. When I played it few months after that, I found myself liking it a lot more than when I originally had tried it. I think I had just gotten better at shooters to be able to properly play it, I remember dying a ton of times during the free weekend and being frustrated about it. Fast forward some years and now I'm sitting at nearly 300h playtime on the game, and have several other Borderlands franchise games in my library (almost all of them played). So could definitely say this win deserves to be mentioned. :D

Torchlight and Vampire survivors

Hentai Pussy 2.

Days Gone. Forgot about AC Origins Gold, also awesome game

Several
But I will go with the following 2

Alice: Madness returns
War of the Human tanks.

There's a couple.
The Hexcells trilogy is one of the games I clocked most hours in, and I replayed every entry in the series at least three times, if not more.
Then there's Pillars of Eternity, which introduced me to CRPGs, and I loved it.
Divinity: Original Sin did the same with turn based gameplay.
And then there's God of War, and actually a couple more, but that's enough for now.

Moonlighter :)

Surprisingly, turned out to be The Walking Dead from Telltale, after playing it, I bought the sequel, and now, thanks to the sale, finally bought The Final Season too

Hacknet labyrinths (it made me play the base game too), reminded me of the time when we typed commands on amstrad ;
progressive didactic difficulty, inventive puzzles, i didn't like the tight timed aspect of some puzzles though.

For me it's the universim. Not because of the game. Only because of the odds. I won against 3,000 people. That time i understand i can win anything on this site.

Ryse: Son of Rome. Definetly this one!

Hollow Knight! My second favourite was a game I won just after that game, namely Tyranny.
I've tried to be pretty selective with what I enter, so the vast majority of the games I've won have been games I've also enjoyed.

The Dark Pictures Anthology: House of Ashes

Probably Supraland

Immortals Fenyx Rising, really enjoyed playing that game, wish it was longer and i had some other nice wins but from everything i won so far Immortals Fenyx Rising stands out the most for me

Inkullinati - The turn-based combat game with medieval-esque artwork.

And my favourite game that I won from a Christmas giveaway train was the Burglar Simulator, which i more enjoyable than I expected.

Killing Floor 2 I suppose. Wasn't really into first Killing Floor much(even if it had better atmosphere or gunplay) but KF2 really got me hooked,namely leveling up Demolitionist and Firebug class.
