Is it any messier than publishing?Otherwise, I agree. The state of RPG design is a mess. There are some ideas out there that aren’t bad (e.g., I like a lot of what Baker says because it tends to be focused on design rather than play), but there are few examples of designs done from the ground up (particularly based on these ideas). So many people just take a game and rework it, and I’m not interested in that because if those games did what I want, I wouldn’t be designing my own.
That's like saying we haven't figured out how to write the best book yet.
What is the audience? What is the genre? Is it a technical manual? What is the language? Should it be a hyperlinked PDF? Should you include interactive components? What about the font, layout, text size, paper quality? Hardback or softcover?
We could ask similar questions about film, music, or any other creative pursuit.
If this guy knew half as much about gaming as he brags, he'd not be calling out games as "bad." Different games for different purposes.
