Captain N: The Game Master
Though the world based off Dragon Quest is referred to as Dragon's Den, elements from it and the Dragon Quest series appear in two episodes of Captain N: The Game Master such as the Dragonlord and some Slimes.

Fortune Street
Alefgard appears as a playable board in Fortune Street. In both sets of rules, the board resembles the continent as seen in the Dragon Quest series, with four large landmasses and an oval shaped island in the middle. In Tour Mode, the player needs to get first or second against Angelo, Birdo and Dragonlord. When playing on this board, Erdrick is mentioned by various characters.
