How is it wrong, even mathematically 6 is a smaller gap than 36.
Trust me, I get that games are interactive and I love them for that aspect. Let me use Uncharted 3 as an example, I'm a huge UC3, really the only thing that has ever fulfilled that wish of wanting to "play a movie." I've seen the 60FPS video of the desert that was released and I don't like it at all. There is something more layered about the 60FPS video, it's almost as if Drake stands out amongst the environment as opposed to being there. It feels "off" to me, maybe its because UC3 wasn't developed with 60FPS in mind and that the video is a conversion. Maybe my mind will change when I see it implemented better.
I do know that I have played the Order and my enjoyment of what I played was not hindered or handicapped by 30FPS. Trust me, if/when you see it in person you'll see how dedicated they were to trying to recreate the visual sense of a movie9 (CGI film as a better comparison). The focus was not how fluid the character moved, objects, moved, etc. With it being 60FPS, the character didn't visually stand out.
Things seemed to mesh better overall. I'm not saying 30FPS is inherently better, I'm just saying everything worked with the look The Order was trying to create. Truth be told, it made me appreciate the black bars as well. 30FPS isn't necessarily a "weakness", its an aesthetic.
Videogamey isn't a bad thing, but when you are actively working against that look, it helps to not rely on techniques that would only be counterproductive .
