Just came back from a local Comiccon and they had a Playstation booth with VR games and GT Sports.
This was my first time trying any kind of VR.
I'm sold!
The game I tried was Rigs. When I put the helmet on it took a bit of adjustment. Don't know if it was the helmet itself or the guy helping being inexperienced but after a while it fit perfectly. It wasn't too tight. I tried it only for 10 minutes so I don't know if extended play sessions would cause some kind of comfort problem but there wasn't any during my playtime.
At first it was definitely a "holy crap!" moment. Looking down and seeing my character's hands instead of my own sent me chills. Then the guy went "you can look at the back of your mech", so I did and it was amazing. I had concerns about how faithfully the in-game camera could follow my head movement but they were put to rest pretty fast. It really is 1:1. Looking at my teammates and being able to freely look around without using thumbsticks for the first time was an awesome experience.
A negative. When I first put the helmet on I immediately noticed the
grid of the pixels. You know like the mosquito net on a door? That's how it was a little bit. Not that noticeable mind you but it still kinda was. After about 30 seconds I stopped noticing it completely.
Rigs was a cool game and it looked nice. Very colorful and very responsive. One thing I'll definitely have to get used to if I buy a headset and I start playing regularly is constantly having two ways to control my viewpoint. Both the right stick and headset enables you to look around. One is your mech, the other is the head of your character. Sometimes I wanted my mech to turn but instead of using the right stick, I looked to the right.

At first it was very difficult to control but at the end of my 10 minutes it was a lot better.
The game itself was difficult but the controls felt tight and responsive. Even though I was struggling with the controls, I always felt that it was due to my inexperience with VR and more specifically this game, rather than a shortcoming on the game's part.
In short, what I got from my PSVR experience is that the good definitely outweigh the bad. Those are not the best graphics I've seen and the grid/resolution problem can be a bit distracting but the immersion is there. It's all in the execution as they say and in this case Sony very nicely pulled it off. What I wanted from VR was a solid product with decent support and, most of all, something that felt fresh and new. And it delivered on all of those. I just hope the launch shipment will be enough to satisfy everyone or that we won't have to wait too long for new shipments to arrive.
