What do you need for the VR setup for Playstation? My brother has a PS4 (I think it's a non-slim, non-Pro, if that matters) & I've been seeing sales on the PSVR stuff all over the place, although it looks like the base version is missing all of the stuff you need. If I understand it right:
1. Playstation 4, 4 Slim, or 4 Pro
2. PS VR games (disc/download/both?)
3. VR headset kit (HMD, processor unit, cables, etc.)
4. Camera
5. 2x Move controllers (Wii-style things)
6. Aim controller (gun thing, optional)
Not sure if having him piecemeal it would be a better deal or not.
Minimal items needed is the headset + camera. Some games require move controllers, some don't. Some have control schemes with both but usually the move controls are more enhanced.
The Aim controller was bundled with Farpoint and works incredibly well with it and it's an outstanding peripheral. It works with Doom and a few other games too however it's not integrated quite as well (from what I've heard). There is a game coming out in April that was built from the ground up for it as well called Bravo Team which is supposed to be similar to Time Crisis except you control which points you move to. But it's not free control to my knowledge unless they have changed it.
Some games are physical and digital, some are digital only, just really depends.
PSVR works on non-Pro PS4 but the quality of graphics isn't as good. I haven't tried it so I can't compare. But in general, the resolution is noticeably not as good as a PC VR unit. The first VR I tried was the one at the MS store and then tried PSVR and I could instantly notice a FOV and resolution difference. But it still is awesome and doesn't really take away from it.
I personally got the Skyrim bundle because it has v2 of the PSVR, which has HDR pass through and a few other minor tweaks, such as thinner wires and the headphone jack/placement is different. I also recommeud using over ear headphones because it adds a lot more immersion.
