I'm not saying it's easily accessible by any means, but you can definitely get a headset for a good deal less than $1500, and many (if not most) games can be played sitting at your desk in the same position you'd be in if holding a traditional game controller.
I agree it sucks that there's no non-VR version. I just wanted to say that it isn't exclusive to the obscenely wealthy or anything, if you already have a PC capable of running it you're likely in a position to be able to swing getting the gear for it.
