Educational+Game+Directory

=Educational Video Game Directory= In general, this directory emphasizes 'complex' games (games comprising of a variety of activities, typically taking multiple hours to complete). Short, single-activity 'mini games' are typically not listed. Also, please note that from a strict definition many educational games are not 'educational'; They aren't designed to teach the player new (content area) skills, knowledge, or content, but rather designed to motivate the player to review or practice skills, content, or knowledge the player has previously learned elsewhere (i.e. Distributed Practice).
