It's a thread about a video put up by EA. As long as talk sticks to what's in the video, I really don't see the issue.
And yes, clipping is a thing in pretty much every game. But clipping is not something that "should" be present, and there are different levels of clipping. If I play GTA and walk right through the back half of every car, that's bad. Just like if I go to tackle a player in a football game and the players arm goes through the leg, that's bad.
I know why clipping happens, and I know there's no way to eliminate it completely, but the jobs of the game developers is to create the illusion that these are just more than blocks and wire frames running around a plane. Things like that break that illusion. If the physics were more dynamic, I may be a bit more lenient, but what's in this clip is an eyesore. Just saying "It happens in every game" does not excuse the severity of it.
And it's really not even that big of a deal as it's not gotten to be, but it's still an issue.
