VR has correction for your eye's inability to focus on super near objects, and can give you the perception of more depth, where just getting close to a screen will NOT do.
With my glasses or contacts, I have 20/20 vision, and sitting 12.2 feet back from a 100" wide screen, I cannot see individual pixels in a 2k (1080p) on a still image, and when in motion, it is perfectly crisp and clear to me. I could argue that almost 100% of people couldn't tell in a blind test (not blinded, lol, blind) the difference between 1080p and 4k in the same room with the same movie on a 100" screen, but that horse is already beat up pretty good. Suffice it to say that if your eyes can pick out the difference between 80 pixels per inch and 160 pixels per inch on a moving screen 3 feet away, your vision is extraordinary and bordering on superhero status.
HDR (high dynamic range) combined with 4k is another story, and by the end of the year HDR 4k screens will be in abundance even though it will still take a few years for content to catch up. Personally, I am contemplating upping my screen to a 120" or maybe even a 2.35:1 screen at about 120" (which is a couple feet wider) while still using 1080p because I know I won't miss out on anything.
As for gaming, it isn't much different to game with a 32" at 2 feet than with a 100" at 12 feet or a 100 foot cinema screen at 80 feet back. Get closer and you have to move your head too much to see the extent of the screen. Get way too close and you have to focus differently from one point to another, and after a few minutes you will be dizzy, nauseous, your eyes will hurt, and you will probably be miserable.
Now, plug in to a very well set up home theater sitting in the "sweet spot" with a 7,000 watt system powering the audio, and you will have an experience. Playing an FPS might still get you sick after a little while, but it is so worth it... lol. Anyone in Montana is welcome to come over and try it out for themselves...
