So only playing as seemingly heroic vigilantes?

Nah. You'd get to play as superheroes/supervillains. But rather than using superpowers or advanced technology, you're limited to modern utilities. Unlike Batman, who was inspired by the legend of the Zorro and classical literature amongst mythology and psychology, you're characters are inspired by the comic book superheroes and their mainstream appearances. You can genuinely be heroic, you just can't have a system of crime-fighting/law-breaking without the 'kinks' of superheroics/supervillainy.
