Given the empty space on my single gaming shelf and my almost complete lack of use of purchased gaming products when I am GMing, it appears that I am somehow aberrant. Does this lack on my part exclude me from the OSR? If one takes Tenkar's ad hoc definition of the OSR to an illogical extreme, then yes. It is a good thing that stuff like this causes no loss of sleep on my part.
I am not going to quibble with Tenkar's definition because I think it is captures where the OSR is today. It is interesting that the focus of the self-identified OSR has shifted not-so-subtly from "process" to "product." It seems we have gone from rulings, not rules to products, not rules. Certainly there has been a desire from the beginning by many to create OGL-based rule sets that would, in turn, serve as platforms for other published products.
I have good friends who are avid producers and consumers of gaming products. I am happy for them and excited to watch them benefit from their creativity and hard work. Technology has provided marketing and distribution solutions for both producers and consumers. Oddly enough, instead of jumping in myself, I find myself becoming almost Amish in my approach to gaming. No fancy cars or electricity for me.The more there is out there, the less I want it. I have purchased only those items (mainly rule sets) that I knew I would have to use for gaming sessions. But that has been it during this past year. No Kickstarters. No Patreon. No adventures or supplements.
The funny thing is that I buy far too many books. I have thousands of them. Despite this, I am always buying more of them (mostly cheap used ones through Amazon). With music, I am both a consumer and a producer. I make money playing music but it just results in more musical instruments in our house. But when it comes to gaming, I just need my dice and a pencil.
