Paizo is really the only "other business" that puts out remotely the amount of product we're discussing though. Not Cubicle7's The One Ring, nor Fantasy Flight's Star Wars RPG... hell even World of Darkness which is famous for the amount of product White Wolf churned out in the 90s has a much more limited release schedule today under Onyx Path... none of the rest put out a hardcover monthly. Only Pathfinder.
Yeah, I know. I like to try to use synonyms when I write. They aren't always adequate.
To be frank, I'm pretty tired of the "Paizo does it differently" argument. But I still use it, right? Like I said, it is the elephant in the room. Hard to ignore.
I'll call it now. Two years from now, that will not be the case. Either Paizo will throttle back the pen and paper release schedule dramatically, or they will have to release a Pathfinder 2.0. You were the one who posted the link to a store owner stating "Boring Pathfinder releases have hurt Boring Pathfinder sales." There's simply very little exciting content left that Paizo hasn't already covered, and we're currently in the long dark teatime of the Pathfinder fan's soul.
Maybe. I'm thinking PDFs changes the dynamic. They are cheap, you get them immediately when you buy them and they are subjected to impulse buy. Paizo prints a limited number of their books (except the core book). Once they are gone, they are gone*. But PDFs stay, have been paid for and they have a low inventory cost.
Someone is starting a campaign in Cheliax**? They can go shop for the Cheliax supplement even if it is out of print. When shopping they will also see other stuff. They made a supplement about Devils and Hell's hierarchy? Cool, I'll add it to the pile, it is cheap. Champions of Corruption? Cool, my players will dig that! Legendary Games made a supplement about Mythic Devils and it cost 5$? Sure, it refreshes old monsters.
So initially it was supposed to cost 12$ and now it cost 30$ and the OGL was useful.
Wizards has been through this process twice already, and decided they're not interested in oversaturating the market twice in a row. This is Pathfinder's first rodeo, and they've done phenomenally to date, but now they're going to need to change tactics if they don't want to get thrown off the bull.
It is true that there were lots of books printed, but what hurt 3.5 is World of Warcraft. Ryan Dancey mentioned it in a vid. There was also that whole "brand must make 50 millions or something" policy that Hasbro imposed. It killed 3.5 and paved the way for 4e. It is true that a lot of books were printed for 4e, but a lot of people seem to use it as the reason for it demise. It is sweeping under the rug the fact that it just wasn't a hit with gamers.
Now I'm not saying that saturation doesn't exist. Just that WotC's release schedule, at least what we know if it, is a bit extreme.
*There are exception for very popular books, like the Distant World supplement. It was so popular they reprinted it.
**Sort of a fascist state under Asmodeus' thumb. Lots of Devils and pacts with Devils.
