I agree it is a dirt cheap hobby if you want it to be. And
because of that, I increasingly don't see the value in buying a bunch of new systems. For example, the "gold" edition of the newly released
Crown and Skull is $80. That strikes me as a quite expensive book. Is it a good value? Perhaps if C&S becomes your main system and you end up playing it a lot. But
as a book, and compared to other books (say, the complete works of Shakespeare), it does strike me as pretty expensive.
There's a lot of this sort of gratuitous stuff in the hobby. One of the ironies for me of the OSR, for example, is that on the one hand there is this emphasis on embracing the DIY, dirt cheap aspect of the hobby--"
folk dnd" if you will. And on the other hand, a kind of preciousness around book quality--the paper, the binding, the ribbon bookmarks etc, which sometimes seemed geared more toward collecting than playing.
