I would love a superhero game that isn't just about wearing tights and beating up crooks (or solving puzzles), but also one where you have to balance your alter ego's social life, etc. Like, take Persona 3/4's time management and apply it to Spider-Man: school's out, do you a) study for your midterm tomorrow? or b) websling across the city?
I like that idea. Would be a nice connection to the various Spider-Man stories of Peter Parker not always being there for his friends when he said he would because of being Spider-Man, or his worry about not being there when he is just being Peter.
I would also enjoy something to the affect of Beyond Good and Evil's camera to money play. Not just a mini-game for more experience points, but an actual game mechanic that matters to the story to keep Peter from being homeless or afford all those webs he shoots or Aunt May's health medicine.
I have spent too much time in various "Can Superman ever have a good video game" (the answer is yes) type threads thinking about aspects such as this. One of which is the idea of a Clark Kent, investigator reporter video game where the Superman bits are just there for action missions and it's the detecting that would be the main focus.
Connected from that, The Question (not JLU cartoon mad conspiracies man, but investigator reporter of original comics). Stealth game play to find criminals or corrupt politicians, some fighting to get to an interrogation, etc. Alpha Protocal or Mass Effect style dialogue options would be nice.
In some other thread. Green Arrow, where you act as a business man working on business aspects to improve the city in a Assassin's Creed II sort of way or Dark Cloud or ActRaiser. Then the night time segments, hunt people in a Dishonored style "small sections of open choice"
Zantana, one of the oldest super heroes, imagine if it was like Heavy Rain. Complicated spells and hypnosis and other magic trickery that we might not actually know is real or not in that world, but get a fun story out of it. Do that for both magic entertainment shows or stopping criminals.
Johnny Storm of the Fantastic Four. A known male whore constantly going on dates for the attention given to him for it to boost his ego. Has to be a romance sim in that between segments of fighting some alien space bug.
Not all great fun ideas I'll admit, but would be nice to see them actually expand beyond the all too same rough ideas and "beat everything up" super hero based games have always been once technology allowed as such.
Sadly they only time they try is a bad attempts at movie tie-ins like Spider-Man 1-3 movie games where you had the segment of getting Peter to his apartment in time for a date, but was not good game play at all because it was just an excuse to move the story along rather than actually mean anything.
