Well from playing one of these . what I know you can make your own"room scale" or stationary boundary.How much space do you need for a vr setup and a game like this? I'm thinking Oculus 2
With room scale you take the controllers and draw the space where you'll be playing. You step out of that boundary you get a message. So say you in you living room if you were to overstep into say your kitchen it would show you.
With stationary it's like one s stationary circle where you can't move outta that circle.
