OD&D is a working RPG which was run and enjoyed by so many people that it spawned a genre that was instrumental in producing your personal favorite RPGs, and it continues to work for many people.- OD&D works differently from (say) third edition, Fate, or Dungeon World. Not just in the details, but in very broad assumptions. These functional differences matter; even if they do not matter to you, they matter to me and others.
- RPGs live in different parts of design space. They do not simply move forward on a timeline of technological progress, where whatever big publishers or the "indie" scene produces simply makes past RPGs obsolete. Rather, fashions change and different corners of design space are explored or returned to.
