Why would you name a gaming adjacent system “PortalVR”? I doubt you’ll get in trouble for it but you’re going to confuse so many Portal fans (and there are a lot of them).
I put "real" in my sentence explicitly to exclude these little control demos. Half an hour long, no portals, whatever sense it's a "very real" portal game is getting outvoted by the other senses.
I was going to name it Portal, but I named it PortalVR to minimize confusion.
It’s called PortalVR because there is no better name to describe what it’s like to play VR this way. It is like playing games by looking through a portal you hold in your hand.
