Dungeons & Dragons: Tower of Doom was Capcom's first D&D arcade game, and while it borrowed from existing hack-and-slash games such as Golden Axe, it added a fair bit of complexity to the formula, with distinct character classes, a range of magic spells, more complex combat, inventory management and branching story paths. Tower of Doom features a fully TSR-approved D&D storyline, including taking place in D&D setting Mystara and featuring iconic D&D races and enemies. The game's success led to a sequel, Shadow Over Mystara, which further refined the graphics and gameplay.
