1st, Oldest wins
Aquaria. (14th win, 0 achievements, 42 minutes gameplay)
Also I hope I can do this for a year with at least 1 game a month: playing a gift as well that I got from people. For christmas, birthday, or just got the game key because no specific reason.
So to have a similar one - gift from TheZooZ, 2016 christmas, The Aquatic Adventure of the Last Human.
Much sea, very salty, wow!
edit: and Aquaria is 100% now! :3

Will be going for Untouched Wins this month

Yay for another whole year of SG wins.

I'll go for Most recent wins challenge first

#2 Most recent wins:

starting the year with one of my freshest wins.... :D
and planning to go on with a less-newer one... >_>

.hack!!!!

I'll pick Challenge 2 (Most recent wins) this month

Honestly I am not sure if I'll manage this month, since I still have a huge game going and just now started another huge one for the blaeo monthly, buuuut if I do, it will be:
Hustle Cat

Will probably be busy with some of my direct gifts for the first half of the month, but will try to squeeze in a SG win after that as well (Will edit after I make up my mind which one I'll play)

The Holiday season has been kind to me on steamgifts so I'll start the new year playing my newest wins.

Happy 2018 everyone :)

I'll go for a custom challenge this month: "Play a game from those you won the most of"

I'll probably regret this but I'll go with Oldest Wins and Pixeljunk Monsters Ultimate.
EDIT: failed.

I'll go with 1, oldest win, which is Saints Row 2!

2. Most recent wins
I need to start some relaxing and casual games to accompany the more engaging ones that I'm currently trying to complete, and I was lucky enough to win some good stuff of that kind lately.

First time participating! Yay!
I'll be playing my very first win, at last, which is Lord of the Fallen.
It still remains untouched, but I've finally got some time to play it!
So I'll go for Oldest wins and Untouched wins .
Here's the achievement page

EDIT : Well, it looks like I'll have to give up on that for the moment, since my PC is not currently powerful enough to make it run, and the game kept crashing

This month I'm going to beat Borderlands 2, which I won couple months ago. It falls under challenges of Long, Unfinished and Wishlisted. At the moment of this posting I have about three hours of game time, which comes from me testing out the game during its free weekend back in 2014 and hopefully now I'll be able to beat it!

I pick The Long Dark
It is fitting to challanges:

4. Long wins
5. Untouched wins
6. Wishlisted wins
7. Month/season themed games

STORY MODE FINISHED

Neglected wins.
I will try to finish Grim Fandango Remastered, which I've won from our dear Harry (Olarte) over a year ago.

Wishlisted wins

Shantae and the Pirate's Curse

Untouched win since I just won it :P

Edit: Finished

Let's start with the most recent short games :D

My first one in here is for the Untouched wins-Challenge:

Hand of Fate | Achievements | Status. beaten

Challenge number two

Game: Maldita Castilla EX

Status: in progress

2. Most recent wins

I somehow missed this post this month. So better late than never...

I choose "Oldest wins" for Poker Night at the Inventory, my third win ever (and one of my luckiest with 1610 entries). What's also neat about it is that it's the only sent gift for the GA creator.

Current progress

I'll start with Most recent short wins ;_;

Yay ready for another round! :D Last year I beat 15 SG wins through these challenges. Starting off 2018 with 69% of wins beaten.

11. Month/season themed games - Won/Played in January

I'll probably regret this, but how about a challenge?

This is exactly what I needed. Please, challenge me.

Go ahead! :) As most of my games goes from wishlisted wins, then it is hard to pick myself. :) ATM I am in 7 Wonders 2 and slowly finishing 100% achievements in KF2, but I can deal with something new aswell.
BLAEO

I'm too lazy to pick so I would like for someone else to do it for me :p.
All I ask is they pick a min. of 3 of mixed lengths.

Pick a theme, and go with game(s) that fit its rules. Also some people list more than one game because they think they can manage more, while others do it to provide some wiggle-room (completing one of them)

I'm pretty sure it's just one challenge per month, but for some people one challenge is not enough :)

They might run out of challenges though because one challenge can be used no more than 4 times per year.

View attached image.

Though the goal is to complete at least one of these challenges a month, the main thing is to just play your SG wins.

I wanna participate but have limited wins left to play/might not be able to play much one month. So I'll be doing a different challenge for every win I beat, even if it means completing 3 challenges one month. I'd rather play while I'm in the mood and still count towards challenge than none at all! The rules are pretty loose and ultimately for fun/playing wins, I'd just do whatever works best for your schedule. Though it's 1 game per challenge, lots of people have more than 12 wins anyways. Can always beat a couple games towards one challenge too. :)
