I find the unboxing before release quite silly, what exactly are you going to show, the poster or something? I do agree with the other things though, while I find that the whole, "it's alright if there's commentary and it's part of a bigger playthrough" is kind of hard to really judge what is and what isn't at times, it's a good general easy to follow guideline. I approve of this, and hope more companies will start making these kinds of statements (or maybe have it be a part of the users agreement that most games have)
