A family of games that feature superheroes as part of the theme.
"By strict definitions, characters require actual superhuman powers to be deemed superheroes. However, this term has also been applied to costumed crime fighters, characters without super powers, who perform the same functions as superheroes. Broad interpretations of the superhero genre included masked vigilantes, who fought crime with their wits, fists and guns rather than superhuman powers."
