Wizardry I•II•III: ~Story of Llylgamin~ is a remake of the first three Wizardry games: Wizardry: Proving Grounds of the Mad Overlord, Wizardry: Knight of Diamonds - The Second Scenario, and Wizardry: Legacy of Llylgamyn - The Third Scenario. All three games are available for the first time for the Super Famicom in this compilation release. As in the original games, the player can create characters choosing from five races and eight classes, and level them up by exploring the maze and fighting monsters, finding and buying items in process.

Monster graphics have been updated, and dungeons have been given textures, but the player can also opt for original graphics with wireframe dungeons. An auto-mapping feature has been added. The player can also transfer characters between the three scenarios.

Though released only in Japan for the Super Famicom, the game can be played almost entirely in English by changing the corresponding settings in the option menu.
