Okay, 100% serious - this is pretty fascinating stuff.

I'll admit that, as an MMO newsie, I see a lot of talk of new MMOs that do things new and different, and I've gotten fairly used to them. The talk of Firefall having staged content didn't seem terribly interesting to me at first, but having seen this video? I realize its impact. Extra Credits accurately talks about why this game - and this feature - are so critical to how they're going to break the mold. And now I'm adding it to my 'Worth Trying' list.
