Learning is tough. Student performance is based upon their ability to remember and apply what is learned. Learning is hard because our brain chemistry resists change, unless the brain deems information important enough to remember for its survival. The brain determines importance based on context and relevance, found in the way in which information is delivered. If information is deemed irrelevant, it will be mostly forgotten within 72 hours.
Video games that allow people to discover and experience ideas for themselves represent a seismic shift in the way learn and grow. Discovery requires exploration, play and challenges that keep moving the destination (goal) ahead in reachable increments.
People who discover something for themselves own that discovery. Experiential learning required a shift of focus for teaching from epistemology (knowledge) to ontology (being). To gain experience with a subject a student has to develop and express mastery. In an experiential video game, players are allowed to explore and discover. Players invent, try, succeed or fail in rapid cycles. Games have an uncanny capacity to stimulate our brains. The best serious games use that power to stimulate learning.
