You need to have a passion for what you are going to be doing in VR. It's easy to fork out big money on the best headset and all the peripherals, and when you first look round, it all looks amazing.
And then after a while you get used to the amazing and then you're thinking what next?
Passion for what I'm doing? I'm going to be shooting the **** out of aliens and people and stuff. I plan on spending what I need to spend to play half life. I literally haven't looked at any other titles but do play a bit of Project Cars 2 and Asseto Corsa and have that fancy steering wheel. I hear those games are decent in VR.
i would say, if you get the Rift S, then dont bother with the index, not worth the upgrade FROM the Rift S (no idea though, what do people think?)
i would google comparisons between Rift S and Index
do you have a large play area?
I have a play area that can be, I don't know, the room is about 20 odd meters squared and all it has in it at the moment is a desk. So plenty of room available. How much room do you need?
