For one, it's not a walled garden.
Indeed the Vive helped stop that.
Two, "probably no motion controls" is as bullshit as me suggesting that without the Vive the Rift would have "probably" come with a free blowjob.
That's why the Rift comes with a Xbox controller, right? Only problem was you can't back out of a deal once it's been made. Also that little stupid controller they ship with the Rift. All of that cause they always planned to have motion controls right, it's not that they rushed the HMD out the door so it'd be released early even though the controllers are still months off.
"Probably worse" too, as they tested Valve's VR room which is not the Vive.
The HMD was, it may not have been the Vive but it was a prototype of what would eventually become the Vive. Semantics but my point stands.
Like you cold program a feature that relies on the Vive wands hey? But that would just be poor design. There are a lot better methods that don't involve novelty.
That's not even remotely the same. The wands gives the game spatial awareness of where the controller is. Alone it would be pretty horrid and novel, cause you'd have to be interacting with a flat screen that you can't really look around with. It was called the playstation move or something stupid like that. Completely failed. Sure there's the wii controller but it wasn't very accurate in it's detection, it interacted with the screen in a 2D manner and Nintendo is just really good at making fun games even if the controls aren't perfect. Add in a head mounted display that displays a different image per eye that gives you some sort of spatial awareness, as well as being motion tracked as well and it becomes something completely different. There is no alternative to being able to reach out with your hand, being able to tell the approximate difference to an object like a gun, pick it up, be able to rotate to access features of the gun. Such as loading in a magazine, tiling the assault rifle sideways to be able to reach the lever that's on the other side and cocking it so that the first bullet enters the chamber. Please, tell me in what fucked up world do you think that is the same as your rumble example. Oh a rumble? Easily replace that with an icon that pops up on the screen with a sound. Now please, replicate the VR experience of the gun with a Xbox controller. Your deluded if you think that is anywhere near the same situation. Your example was BAD, just BAD, plain BAD. You can't argue out of it, cause it's bad. I know you will try though, gl.
