They would absolutely nail the level design, atmosphere, exploration, and the sense of discovery, dread, and wonder that the IP has missed since the PS1 era.
I would like a Mafia Definitive Edition-tier remake of Grand Theft Auto: Vice City or Scarface: The World Is Yours from Playground Games with their amazing driving physics, world design, and visual fidelity shaping the 80s Miami inspired locations.
I would also love a Teenage Mutant Ninja Turtles game with a playable Casey Jones made by Team Ninja set in early 90s New York.
