This is gonna sound really weird, but hear me out on this:

A Danganronpa fighting game.
Every character could have their own unique playstyle based on their talent. Characters like Sakura and Akane could be your average brawler, whereas characters like Souda, Naegi, and Chihiro could have more creative movesets. Chihiro could set electronic traps and such (think something like Naoto Shirogane from Persona 4 Arena) and Souda could use some kind of machine to fight (think Tron Bonne). Probably just my nerdy fantasy, but a guy can dream.
