This is just beautiful, from the title ("Brave Noob World") to the idea -- a geographical survey of Azeroth. James Wallis, the director of Hogshead Publishing, gave this presentation at an "unconference" called Interesting '08, in which he tried to do a survey of Azeroth, in the same way that Tobold did -- by walking from one end to the other. And he discovers that Azeroth is pretty small and pretty dense -- it's about 12km across, according to him (I really like his comparison image of the Death Star), and using a Female Tauren, he even comes up with the force of gravity, which is about equal to Earth -- about 1g. Which makes sense; Blizzard would want the virtual world to feel the same as our world, no matter how big it is.
There's a problem with that, though -- if you have a small planet with the same gravity as a much larger planet, the only answer is that the mass of the planet is much more dense. And when you get a really small, densely packed mass, you start to mess around with the flow of time. So Wallis actually ends up explaining one of the more annoying features of Azeroth with actual science. Very nice.
It's definitely a fun example of looking for more in this MMO than Blizzard probably put there, but Wallis covers it with enough zest and logic that it works, strangely. Now if he could only explain the weather...
Update: Looks like the video got pulled. It's been stowed after the break, just in case it comes back.
