Yep, I know about that one, and it's VERY good. But I wouldn't put it in the same category as the DFA doc, with the latter one being MASSIVE! (which I was referring to)
I've watched the bits of 2PP's Minecraft documentary that got released and you can clearly see 2PP's style in it. But again, I don't thing there's anything rivaling the size of the DFA doc (again, in the video game sector, as apparently "Planet Earth" and its siblings are yet another caliber).
And regarding a doc about LucasArts... it could be a comedy about the president's chair seeing a LOT of asses.
