I just watched the AD&D round table. It was good. Mostly people reminiscing about their experiences playing AD&D, how they got into the hobby, a bit about the Satanic Panic, etc. Nothing much about design (as to be expected). One thing that stuck out was the comments on the "incomplete" nature of the rules and prevalence and/or necessity of house rules. I'll always think of house rules as a feature not a bug. Always. It was great to see them commenting on how that made the game theirs and how needing to fill in those blanks started a generation of game designers. There's something to be said for making the audience work a little bit for their meal.
