The Steam Winter Sale has started. Runs until January 4th.
It’s the same setup as the holiday sale. A ton of games on sale with highlighted deals posted on the main Steam homepage daily.
You can earn exclusive winter trading cards by exploring your personal Discovery Queue.
Do note that games could be added and removed from the sale at any time. During the holiday sale there were some Ubisoft? (can’t remember exact publisher) deals that ended early.
