This article uses the Skinner Box experiment to suggest that games, specifically MMO's use these techniques and apply them to their game design, effectivity making the game a science experiment to get people to continue to play and well keep the income coming in by the use of subscriptions.

A found a very unique article by a games researcher at Microsoft,he has a doctorate in behavioral and brain sciences, working for a games company.. disturbing to say the least!
