All things considered, you probably shouldn't watch the No More Heroes 2: Desperate Struggle dev diary we've posted above. It's pretty NSFW, it's chock-full of spoilers for the original Heroes (and even some for the sequel!), and it features more shots of Suda 51 sitting on the toilet than we're really comfortable with seeing.
On the other hand, it also sets a new precedent for how enjoyable these developer diaries can be. Instead of a bunch of dudes sitting in a dimly lit room talking about how awesome their game is, it's just Suda, sitting in a bathroom stall, talking about how awesome his game is, and then his head explodes. We take back the entire first paragraph of this post. If you don't watch the video posted above, then we simply can't be friends anymore.
