What I have found fun/odd/interesting is that VR actually seems to bridge the generational gap between "us" and "our parents" - some of our parents never "got" video games, the disconnect for them is too high, they do not get the "reward" structure nor do they feel anything because it's not "doing" as their "play" was growing up.
VR brings that closer to them, it is more "doing" - I bet your dad liked the move controls better than the gamepad once he adjusted.
Immersion is also a helpful thing, but also it may take a hit with many not adjusting to VR as fast.
Our generation is really the last that is split between "real" play and "vidyagame" play - almost all play that is outside for kids is manufactured, you go to a park, you go to a game, it's not just "me and 5 kids from around town played manhunt for 2 hours around the entire neighborhood"
