into such a simple representation that conveys so much information in such a succinct way. Techniques such as the puzzle flow diagram is an incredibly useful tool I hope he knows that all game designers have to "convey so much information in a succinct way". He can commend Schafer for his craftsmanship, but the format of the game design document is hardly Schafer's own genius invention. To his merit, though, we mere mortals hardly ever get to see this sort of internal documentation, even decades after a game is released. The gaming industry is unfortunately one of the more secretive industries in the tech world. Carmack and others have open-sourced their code, so it's nice to see the designers stepping up and offering their work as well.
