Hmm, on the ebook vs physical book discussion, one argument I feel hasnt been made yet.
D&D (and other p&p rpg's) is this kinda arcane, kinda adventurous activity and hobby. A shelf full of books, pencils, funny dice, some mini's maybe.. these are important parts of this 'romanticised' experience.
Sure, I guess maybe I'm just getting older, not quite in the generation for whom internet & the digital everything has always been there.
I suppose the next wave of early adopters or once digital presence is more accepted, it's technologically & economically a better idea to go to digital delivery.
But I have to wonder if the 'kids' who'd ride the wave of techno advancement are really going for a style of game that is behind the times and kinda... sorry to say it.. obsolete.
Look at people playing guitar.. the materials & styles of the popular models have mostly remained stuck in the '50s. You can make a very advanced guitar using plexiglass instead of wood, digital enhancments instead of analogue electronics and whatnot.. and it's mostly rejected.. because it just isnt the same. With amplifiers, for all their 'obsoleteness' an old style vacuum tube amp is pretty much the most popular choice.
There are a lot of niche artists who make most of their money selling vinyl still, not digital.
imo, ttrpgs are a kinda of hobbyist thing mostly. It's something that sells & plays not only on it's own properties, but also it's nostalgia and romatic value. Taking away that value, and how much does it actually differ from any other type of entertainment product?
