Rocksteady's Superman: 8 Things We Need To See
1. A Lighter Tone
Superman's outlook on life is much more optimistic than Batman's. This is one of the best things about the character. His optimism is what allows Superman to inspire hope in people. The Arkham games played nicely into Batman's Gothic world and his demented villains, but Superman lives by an entirely different code.
The Superman game shouldn't be dark or scary, nor should it be gritty and violent. In many ways, Superman is the opposite of Batman as a protagonist. Metropolis is developed and clean, whereas Gotham in dirty and in decay. Superman inspires hope, whereas Batman inspires fear.
It is very important that Rocksteady recognises the difference between these heroes and doesn't try to 'Batmanify' Superman. Zack Snyder's Man Of Steel tried to take a slightly more serious approach to the character, and was met with a lukewarm response.
A Superman game shouldn't be rated mature because it shouldn't contain disturbing scenes. Superman is supposed to be an inspiring figure, and the game should try to replicate that as much as possible, and it must steer completely clear of any of the grit of the Arkham series (and especially none of the Gothic horror seen with characters like Professor Pyg).
