Stories with/about older characters (35+ years). Like, maybe an MC who actually already did their big heroic deed in their youth (that you would usually see as a game main plot) but now this person deals with the aftermath of that or with the fact that they still feel unfulfilled or are now wondering about their (new) purpose in life.
Hell, I’d even play a game about someone who’s retired from being a superhero/evil assassin and missing their career and trying to find/making a new place for themselves in life.
Example: A retirement home for superheroes/villains (maybe superheroes and villains can co-exist in the same retirement home because they’re retired?). Cue our 80-year-old MC who’s insanely bored and doesn’t want to play bingo with Sheila and Marleen who both smell of wet dog.
MC finds an unexpected friend and ally in their direct opposite, a hero/villain (depending on what you chose your MC to be) who’s equally frustrated with the bad food, the bland conversation, and the fact that all superpowers are forbidden just to keep the peace. Not to mention the fact that the nurses act suspicious as hell and there’s just something about the pills they have to take every day that MC cannot remember their doctor ever prescribing them (dun dun dun).
Sorry for the brainstorming paragraphs. I couldn’t help myself.
