Game Engine White Papers: Commander Keen

All the path the author went through to make sure people mistake him for Fabien Sanglard makes me sick.

• The domain is really similar to fabiensanglard.net
• The page is literally the same look and style. And it's not like Sanglard's site uses any common blog design
• Everything about the book... the cover/title is inverted from "Game Engine Black Book", the layout is literally the same, the writing style, etc.

Fabian himself commented in the thread in Hacker News that he collaborated in the beginning of the project (mostly reviewing), but eventually stopped because the author didn't want to delete fully copied blocks of text and diagrams.

Then the author still goes on and publish it. At least the content is free, although there's an Amazon print version of it.
