Sonic and the Black Knight

Sonic and the Black Knight followed up on the experiment of Sonic and the Secret Rings and carried the same style of gameplay from the tales of One Thousand and One Nights into an entirely different setting drawn from Arthurian legend. Sonic Team retained the proven on-rails structure of fast, linear tracks, but this time armed Sonic with a sword and built the whole game around knightly combat, the motif of the Round Table, and a story loosely inspired by the legends of King Arthur and his legendary sword Excalibur, which is entrusted to Sonic.

Sword combat was controlled by swinging the Wii Remote, with different swing directions corresponding to different types of attacks, and the game gradually unlocked more advanced combinations and special abilities as Sonic gained experience and progressed through the story. Along the way, other Knights of the Round Table with their own abilities join him, supplementing his moveset with additional attack options in certain passages. As in the previous entry, the game's core remained pure speed — narrow tracks full of jumps, loops, and collapsing obstacles that Sonic hurtles through almost without stopping, while battles with enemies and bosses require switching to a noticeably slower and more precise rhythm of strikes, blocks, and dodges before counterattacking.

Although the Arthurian theme brought a refreshing visual style and a distinctive cast of characters dressed in knightly garb, the game did not receive much better reception from critics or players than its direct predecessor — complaints about imprecise motion sensing during the game's combat passages surfaced repeatedly. The musical score and the overall art direction of medieval castles, forests, and battlefields, meanwhile, were among the aspects reviewers rated most highly, even though that alone was not enough to outweigh the reservations about the controls. Still, Black Knight remains an interesting, distinctive detour in the series' history that showed just how varied a range of settings Sonic Team could find for its concept of speed-based on-rails action in the Wii era.
