One of the spectacular things about D&D is that it shifts people into a kind of emotional super-cruise. There have been Edition Wars, OSR resurgence, the Splintering of the Base. D&D has become a thing that demands an opinion or at least a stance before you can even approach it. It fields a cluttered orbit of clones, heartbreakers and offshoots so dense they often obscure the original heartland from sight.
All this anger and emulation, factionalism, jealousy, brilliant insight and recurring humour. It speaks one thing to me.
All those stat blocks, setting guides, conversion notes and rules tweaks out there are like screwed up love letters in the school yard. And we keep writing them.
