This is where it all started, and whoever would have guessed the absolutely massive industry it spawned? Going back and playing it today there's a huge D&D influence to the first game (especially in the magic system) that many probably missed back then.
Needless to say, this is a very bare bones game where the formula hadn't been refined yet. Some of the classes were completely pointless, and the combat system was in need of serious polish (you could actually attack an empty space if another attack took down an enemy), but there's a nostalgia to be had here, especially in that distinctly '80s fantasy box art.
The witch Matoya's backwards talking broomsticks are also a little gem of gaming history that have been referenced in all kinds of media since those heady early days of console role-playing games.
