Asgard's Wrath got me thinking.
VR presents an issue for VR games as to reach the fidelity of flat games they need much higher resolution textures. While the displays may lack the sharpness we want, we are looking at objects much closer than we ever would in a flat game. that room that only spans a monitor now fills your vision. every small flaw becomes massive. 
Game file sizes have to be huge now, AW being 130gb. storage may be cheap be downloading is hell for a lot of people.
