If you know the character and its powers, and aim do it justice, then we are looking at a ronin who’s the deadliest tracker in the world who goes berserk. So you want to be up close to the character, you want a mystery with detective work, you want the action to be bloody, an emotional story with meaningful stakes for the characters (not a save the world story), and ideally you want a wide linear approach to level design that accommodates different kind of gameplay scenarios, from action to horror. The combat itself needs to be simple, say like Sifu is, yet hard to master, like Sifu is.
It’s a hard game to make, difficult to strike the right balance, but in the end if you do the character justice and don’t just make a mindless brawler like your typical dev/gamer would want(because they don’t know the character really), you might just make something that will get people from all types to be enamored with it.
Is Insomniac the right studio to do this? They would not be my first choice at all, but hopefully they know what they are doing.
