Question: Realms of Arkania: Blade of Destiny is a role-playing video game based on a pen & paper game created by who?
Context: A role-playing video game (commonly referred to as role-playing game or RPG, as well as computer role-playing game or CRPG) is a video game genre where the player controls the actions of a character (and/or several party members) immersed in some well-defined world.  Many role-playing video games have origins in tabletop role-playing games (Including "Dungeons & Dragons") and use much of the same , settings and game mechanics.  Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player character development, complexity, as well as replayability and immersion.  The electronic medium removes the necessity for a gamemaster and increases combat resolution speed.  RPGs have evolved from simple text-based console-window games into visually rich 3D experiences.
