Thanks for the answers everyone! There's a cheap PSVR Astro Bot bundle I may buy...
IIRC in Astro Bot your vision is locked to your head
Your vision never moves of its own accord
Which is what causes the majority of motion sickness in VR
Should be very light spectrum in terms of sickness
Damn, I've only watched done videos of the game and never clocked this. My badNot completely true, when Astro moves forwards you move with him. It's a very gentle forward motion though, it's unlikely to cause nausea, and even if you're sensitive and do feel sick you should get used to it fairly quickly.
