The issue is it takes too much effort to play vs normal gaming unless you are able to dedicate a room to it. For people in areas where housing costs are low enough that you can afford a big house, or for people who are single and don't have other people in the house to cater to, this might be fine. But for most people, a good VR session involves moving shit out of the way, strapping on a helmet, putting wrist straps on and figuring out whether you want to do that blind after putting the helmet on or trying to put the helmet on with things in your hands, then playing in a specific area so you don't kick your coffee table (and hope your dog doesn't walk in front of you while you are walking).

Contrast that to picking up a controller while sitting down.

If the awesome games were there to make the extra effort worth it, then fine. But there just aren't the great games yet. I have a VR system and haven't put it on in months because I just don't care enough. It has become a novelty.
