Role playing among kids is a fun way to learn and enhance useful skills in a child's development. It helps them make sense of their environment and for parents too, it's a great way to learn about any struggles your child may be going through.
Why are role playing games addictive?
RPGs are addictive because as you keep playing them, you learn new capacities and continue to discover new and better equipment. The reason for it is a psychological belief that if you level up and open mystery things it won't get boring.
