Tonny Fang says that the challenge with Xcalibur was that the original creator demanded "realism," so all the movements had to be plausible. The characters were not allowed to make movements that a real person could not make, and this greatly increased the difficulty of design.
方俊勳表示，《神劍傳奇》難在原創者要求「擬真」，一切動作都要有合理性，凡是真人做不出來的動作就不能出現，大大增加了設計的難度。
