I can only second that!
It's available on Steam for lots of people to buy; well let us! Add Vive Support already!!
Why anyone would release a game for only one platform is way beyond me... FUCK exclusive titles! They will be the death of VR; more then double of HMDs sold are Vive's.
And nobody is dumb enough to buy Rift-only games, HOPING they will work with ReVive.
