Yeah, they certainly couldn't run every part of every game, it'd have to work like a ratings board where the devs submit whatever footage it is they're not certain about. Which, of course, puts it back on the devs.That doesn't sound like it was a certification thing to me but I'm not sure. I'm not sure how a cert process would even run a test on every piece of the game to make sure it didn't pass the epilepsy tests, whatever they would be.
Would be interested if anyone knows more on that, obviously.
But Sony lost a major lawsuit over a lack of epilepsy warnings a while back, so if there's any part of cert that would involve someone from Sony seeing that epilepsy helmet sequence they would have noted it.
