Rocksteady's Rumoured Justice League Game: 16 Features It MUST Include
4. Make Missions Available To Most Characters
There should be multiple ways to complete each mission, with each character you take in having a different set of skills that can change the gameplay. This might be something as simple as different entry points all the way up to entirely different gameplay.
Let's take the example of a mission to save some hostages from a skyscraper near the docks. Now, characters like Green Arrow and Batman might enter with stealth, slowly picking off some of the more dangerous and better-armed enemies, making sure nobody can contact anyone higher up so that the hostages remain safe. Superman might simply be able to fly through the window, standing in front of the hostages and deflecting bullets. Aquaman may be as much a threat to the terrorists as Superman, but he'd likely enter from the sea. Meanwhile, the entire mission might be a Rube Goldberg machine to The Flash if he enters in Flashtime.
Yes, some of these characters will be so overpowered compared to some missions that they effectively break them, but if the player wants to use their resources that way then that's their choice. As long as the hostages get saved, what difference does it make?
