6. Playable Robin/Nightwing
With Arkham City, we were also introduced to the Boy Wonder Robin, who conveniently was in the right place at the right time to save Batman from what looked like death. With this new game, like my other suggestions, let's take it a step further. If my sandbox/Wayne Manor hub ideas did indeed happen, then why not make it so you have the option of sending Robin out on a distress call and you're able to play as him? I jumped at the chance to play as him in the Harley Quinn's revenge dlc, and maybe even something similiar could be put into the storyline of this game, where Batman needs saving himself and Robin is there to save the day. Since this is supposed to be based on the Silver Age of Batman, the odds of Nightwing don't seem likely since Robin didn't make his transformation to Nightwing until near the end of it. There is a chance that maybe near the end of the game Robin decides to become Nightwing and leaves, setting up the scene for a Nightwing game all by himself, which is something I would like to see as Nightwing really hasn't gotten much airtime in any game, and he hasn't been in a movie yet to my knowledge. Nightwing's time is now, and this game could help to really introduce him to the world. Although I'd like to see Robin as a playable character, there are some characters I would not like to have in my control...
