Here in an excerpt extraxted from the FAQ page of their website at www.spiritualgaming.com - http://www.spiritualgaming.com/sgfaq.html

What is Spiritual Gaming?
Spiritual Gaming could be defined as the use of gaming in the service of spiritual goals.
The general study of Spiritual Gaming is not restricted to any particular spiritual orientation. A kind of one size fits all.
Spiritual Gaming is a concept whose time has come. It is broader than any particular spiritual religion, affiliation, school or belief system, and its potential transcends individual considerations.
What is the purpose of SpiritualGaming.com?
SpiritualGaming.com was established to explore and promote the use of games in spirituality.
Games have been used effectively for self-study, group work, trainings, workshops, counseling, meditations, and even spiritual service.
