Just one more example of the Long Tail to add to the pile: I'm a tabletop roleplayer (have been one for over 4 decades). I have more content legally available to me now than I ever have before. I've recently bought (ebook) copies of obscure RPG material from the 70s that I've been looking for for years. I can easily find quality content for current RPGs (like D&D 5E) even if it's extremely nich, and simultaneously and I buy great new material explicitly written for for AD&D's First Edition!
