I've turned my No Show Conference talk into a 3-part essay series for Rock Paper Shotgun. It argues for a long-standing but suppressed tradition of non-industry involvement in the first-person genre, and that the nascent "renaissance of the FPS" isn't really that recent. Instead, we mentally blocked out the "innovation", then complained why there wasn't any innovation.
Part 1 talks about the Doom WAD scene and the murder of Myst.
Part 2 argues that FPS mods were a way to break into the game industry, so we had to think like the industry too, even if it was dysfunctional / self-destructive for us to do so.
Part 3 observes that many people mod today without any regard for an industry job, and the career path for post-amateur modders is now unclear because of the indie scene. It also argues that many mods are now "postmods" in that they don't care if they ever get played, among other reasons.
