Here is a very insightful article about Play Testing by Compman. The article is currently posted on BoardGameGeek.com. Please have a read, I think you will enyoy the article as much as I did.
The Board Game Designers Guild is a bi-monthly gathering of Game Designers. Meetings
are held on the 2nd and 4th Tuesday of each month at Game Night Games (2030 South 900 East Ste E in Salt Lake City utah).
We will begin at 8:00pm and conclude around 10:00 pm. The bulk of the meeting will be devoted to playtesting.
