title: Is there any sophisticated role-playing game framework available?
body: <p>I'm looking for a role-playing game framework which fulfills the following critera:</p>
  
  <ul>
  <li>Open source / Free for non-commercial </li>
  <li>Targeted language doesn't matter as long as it's not too obscure (C# or Java would be great)</li>
  <li>The framework doesn't have to provide any graphics, sounds or other "low level" stuff</li>
  <li>The framework should support complex, non-linear story lines (like Fallout 1/2/3)</li>
  <li>The character should be highly configurable (again like Fallout or Dragon Age)</li>
  <li>Support for a party would be nice</li>
  </ul>
