It is most certainly not a gimmick, I would go as far as saying it is the future of gaming/entertainment experiences and certainly the best thing I have seen in gaming for many, many years.
I 100% agree, and have been gaming since 1985. Had just about every system, none of them have blown my mind like this. I do have one negative and warning to people thinking about getting it.
Once you play a game like Eve or RIGS, or any of the others really, you'll find it almost impossible to go back to non VR gaming. My normal game of the year, Forza Horizon 3 hasn't been played since I got this, and I have virtually no desire to play it.
So if you're on the fence, finish the "normal" games before you get this, or you may never finish them...
Jase, I wouldn't feed the trolls
EDIT: TV Shows/Movies will give you the chance to walk around in the actual show, in fact there's an app out already(free) which does this in a basic sense. Anyone who hasn't played PSVR for at least 12hours, with different games, really shouldn't comment. You'll look very stupid soon.
