Great VR deals at Viveport: as subscriber (a free test account is enough) you can buy these 5 awesome VR games for €1 each: Arizona Sunshine, Sairento, The Wizards, SUPERHOT VR and Accounting+
They'll stay playable if the subscription gets canceled.
For my free 14-day-subscription I also chose Torn, Transpose, Pixel Ripped 1989, SVRVIVE and Apex Construct.
Most games on Viveport are also compatible with Oculus Rift and other PC VR headsets.
