I like the part where he completely glosses over the fact that D&D is a violent game because it grew directly from wargames. I mean, honestly, the way D&D developed makes so much sense when you realize that the game is a result of a fairly natural progression. Player builds a li'l army. Player develops favorite li'l battalions in his li'l army. Player has one li'l "block" of troops that never lets him down. Player decides he needs some way to indicate that these guys should be veterans by now. Player decides a particular figurine should be a veteran named Bob, who, by the way, has to be kind of tired of infiltrating Castle Blackmoor by now, because he's done it like a million times and has to be like, level 12 by now. Seriously, from the perspective of raw game mechanics, the big difference between proto-D&D and earlier games was the inexorable move from large scale to small scale, which then led to a deeper 1-to-1 Player-Character relationship. The real contribution Gygax made to gaming history was simply accelerating the process and embracing fantasy elements. Acting like it was Gygax himself who invented the world of table top violence is kinda missing the forest for the trees.
