In the opening movie of Justice League: Heroes, Batman gets called to deal with a robot attack. Superman shows up too, and Batman curtly informs him that he didn’t ask for help. Superman gallantly says, “Well, since I’m here anyway,” and joins in the fight.
When gameplay started, I chose to play as Batman, leaving Superman to the partner AI. As I tried to experiment with attacks and learn the controls as well as the enemy behavior patterns, Superman just waltzed up to the robots and destroyed them.
Never has a game so rapidly, thoroughly, and unintentionally created empathy for the player character.
