No doubt much of this is old news for you tabletop gamers. As someone whose RPG experience is limited to several PC titles, most of it is new to me. The tale of Gygax forming and eventually being squeezed out of TSR Games is curious. Interesting to set straight the apocryphal story of the Michigan State gamer dying in the tunnels underneath the campus.
As yet I have not recognised any of the titles in the video games section, I think I may have missed out on some cool stuff.
It all began with a military training tool designed by a Prussian Officer in the 19th century. Heh.
