Arthur appears as the legendary medieval king and playable protagonist in Capcom's hack-and-slash game Knights of the Round and the action-strategy game Legion: Legend of Excalibur. Additionally, the character represents the young hero Arthur Montgomery in the video game adaptations of Arthur and the Minimoys (also released as Arthur and the Invisibles).
In
David Crane's Amazing Tennis (1992), Arthur appears as a playable tennis athlete, rendered via a pioneering pseudo-3D perspective to showcase realistic court physics and player movement. This sports depiction contrasts sharply with the character's action-oriented fantasy roles. The 1994 home console version of
Knights of the Round introduces a dynamic progression system where Arthur's physical appearance and armor visually upgrade as he accumulates score points, culminating in a golden suit of mail.
In
Legion: Legend of Excalibur (2000), the gameplay incorporates tactical squad mechanics, requiring players to manage Arthur's battlefield positioning and special combat abilities alongside a customizable party of knights. Meanwhile, the character's portrayal in
Arthur and the Minimoys (2000) and
Arthur and the Invisibles (2007) focuses on cooperative puzzle-platforming. In these titles, players must switch between Arthur and his companions, utilizing his specific sword-handling skills to solve environmental puzzles, traverse oversized household hazards, and defeat subterranean enemies.
