If you picked up an HTC Vive or an Oculus Rift and need some games for your library, this weekend is a good time to do it. Steam is having a good ole sale of a ton of VR titles. There are some good ones to pick up such as Hover Junkers, Space Pirate Trainer, and Pool Nation VR.
For those that already have some of the titles in the proposed bundle, Steam will automatically remove those games and give you a brand new price. Of course, you can purchase games individually, but if you're looking to grab a massive amount of titles to play with, the bundle's not a bad choice.
