Perhaps PS7 will have enough juice to run more than one VR at a moment =p for local co-op
Actually I have played co-op in VR, forgot about No man's sky. I've been playing that a couple times with my oldest son. It's very glitchy though. I spawn my freighter, it won't appear for him. He goes down to an operations center on a planet, the whole planet won't appear for me, stays a gray smooth ball of nothing. But it's fun when it works and we can walk through each other's bases and add to them.
