A year ago I wrote about the death of Gary Gygax, and what his life meant for the birth of computer games.
All the same applies, and perhaps even more so, to Dave Arneson, who passed away this week. As I understand the story, it was Arneson who took a fantasy miniatures wargame and reinvented it as a structure for collaborative role-playing. That's where we all picked up the thread; long may it continue to unroll.
