Last Saturday, Keith Ferguson ran an UnPub Mini event at Game Parlor Chantilly. (I helped a little.) We had about twelve designers and about 20 gamers playtesting over the course of the 11 hours that the store was open that day. It was about as successful as we could have wanted. For my part, I got to playtest "East India Company" and "Reactor Scram" one time each, as well as to play about four other games, though there were many more I wish I could have played.
