I've been working on this same idea and developing a tabletop RPG engine for twenty-plus years that works on this type of concept. It's my thought that by "practicing" being in dangerous situations with your friends and having to make split second decisions which could lead to drastic success or catastrophic failure, you can really assist people in trust and teamwork when confronted with similar real-world situations, and that a skilled Game Master can help his players become better people... Very interesting, I can't wait to read it thoroughly.!!!
