What I find interesting these days about "true to" b/x retro clones isn't that people want to play that style of RPG. But why buy a retro when you can get the actual D&D Rules Cyclopeida from dmsguild for less than $30 for a hardbound book or less than $20 for a softcover and both come with a searchable PFD. Or digital only folk can get the PDF for $10.
Of course this is coming from someone with a soft cover set of Basic Fantasy Rules. In my defense, I can only say the print option was not avalible when I bought them. And it has nothing at all to do with my RPG rulebook collecting impulse.
