For Spider-Man PS4 we have so many. Primary - area start for Marvel Gaming Universe. Which give us tones of great games about other heroes. There so many ideas for this. And here is couple ideas - Captain America in style of Metal Gear and Uncharted. And about Rocket and Groot - old school beat'em'up with hardcore and 16/32 bit graphic in Skottie Yang art style. And couple other playble characters - Kosmo and Howard the Duck.
