  Playing games has always been thought to be important to
  the development of well-balanced and creative children
  however, what part, if any, they should play in the lives
  of adults has never been researched that deeply. I believe
  that playing games is every bit as important for adults
  as for children. Not only is taking time out to play games
  with our children and other adults valuable to building
  interpersonal relationships but is also a wonderful way
  to release built up tension.
