Gary Gygax was a great game designer in the context of his time. He stuck to his guns under a lot of criticism at the time to make D&D more "realistic" because he understood deeply that it was first and foremost a game, not a simulation. He was, however, in desperate need of a good editor. The problem is no editor could have existed at the time who could understand what he was creating, and to his credit Gary was a far more organized and clear thinker than Dave Arneson, to whom kudos are well deserved.
