Steam tossed some VR experiences into last month's summer sale, but this time, it's throwing a party exclusively for virtual reality enthusiasts. The gaming platform has just announced a VR weekend sale, where it's selling 175 titles for up to 80 percent off. Sure, the selection isn't as extensive, but don't forget that we've only just begun exploring the world of virtual reality. The games and experiences in the list will work with the the Oculus Rift and the HTC Vive, which, if you'll recall, was a collaboration between the Taiwanese company and Steam's creator Valve.
