As a child I was more than happy to spend ~10 minutes waiting for my ancient computer to boot up and load a game, and even now all the League of Legends players cope with absurd startup time. In contrast, it'll take less than a minute to put on some VR goggles. The comparison with 3D TVs isn't so valid. In contrast to gaming, TVs are both casual and multi-user. Making sure everyone has the right glasses to watch 20 minutes of the Olympics (while conversing or eating or whatever) is much different than sitting down by yourself to do some proper gaming.
