In addition to saving on various games, Valve has opened up nominations for the 2018 Steam Awards. There are a number of different categories to choose from. These categories include your overall "Game of the Year," the "VR Game of the Year," your nomination for "Best Developer," and more.
You can nominate games by going to their appropriate Steam page in the store and nominating them for an appropriate category. It's in a big purple box on each page, so it's kind of hard to miss.
