Dave Arneson, co-creator of Dungeons & Dragons, is still with us. Still my sentiments are the same. In any new invention or creation there is always a moment when "it" happens. That the thing you are trying to create emerges from the shards of what was before. For D&D, Dave Arneson provided the "it". He bound the disparate elements of wargaming together into the combination that in Gygax's hands would become D&D.
For that we will be always in his debt.
