If you're up for grabbing some high quality games you might want to check out GOG's "From Wishlists, With Love" sale. It features over 70 of the most-wishlisted games ever (as well as their DLC packs apparently), and it will run for the next five day, or until February 20th to be specific.
You can grab The Witcher 3: Wild Hunt - Game of the Year Edition, Darkest Dungeon, and Dying Light: The Following - Enhanced Edition at a 50% discount, while classic games such as Psychonauts and Arcanum: Of Steamworks and Magick Obscura feature 90% and 75% discounts respectively. All of this is just the tip of the iceberg, however, so make sure to check out the sale for yourself - you might just find something of interest.
I'd personally recommend you go with both the Witcher series and Darkest Dungeon, as those are some of the most fun games I've played in recent years. And if you think I'm exaggerating, think again because I actually spent a considerable amount of time explaining why you should try both The Witcher 3 and Darkest Dungeon, so if you're interested in the details feel free to give the articles a look.
But if none of these games are up your alley, worry not as there is one more promotion you can check out. Humble Bundle has recently unveiled the Freedom bundle, and for $30 you can grab 47 quality indie games, as well as books. And as an added bonus, all of the proceeds go to charity, so I would definitely suggest you check the bundle out. Have fun with the games!
