I have Battlezone, it was the first game I played in VR. It made me a little tiny bit queasy, then I slid sideways off an angled ramp and my brain said "nope". That mild sick feeling went to severe.
I keep meaning to get back into VR, but with Dramamine in my system. I've got a bottle (about to expire) sitting next to my VR helmet, I haven't dived back in yet. I've always been fairly prone to motion sickness anyway, so I think this might not work out for me.
