Enchanted Realms was created to be played as either a table-top version or over the internet using a third-party virtual table application, such as Roll20.net. The rules are designed to keep many of the “problems” of role-playing games limited and to encourage collaborative story-telling rather than sessions of hack-n-slash.
Because of concerns with restrictions by class, too much math and overly slow, complex combat, this game took steps to mitigate those matters. Does it fix everything? No, what system does? But it does address them and offers some variations of the rules to handle different styles of different groups.
