Quest for Glory has finally been released on GOG, all V episodes and both versions of the first QFG.
This finally explains who maintains the ownership for the series. Activision.
Highly recommended for fans of KQ series is Quest for Glory series. It was an RPG/Adventure hybrid series (last game is pure Action-RPG stripped of most adventure aspects). It had a few nods to the KQ series as easter eggs, and like KQ the game took ideas from both fairy tales and myths from around around the world
