Legacy of Batman

Bruce Wayne is dead, and in turn so is batman. this is a game based on my visions of the batman universe, and i would like this to have a similar mood to the arrow and the telltale games, i would like you to assist in telling the story.

characters that you can play as have a few guidelines to better represent the character;
Damien Wayne) has trouble deciding his identity.
Dick Grayson) a political figure who is contempt with who he is.
Barbara Gordon) curious and unable to be a crime fighter.
Selina Kyle) has an uncontrolable desire for wealth.
Tim Drake) knows the batman needs to exist and will do anything for him.
Katherine Gordon) looks up to the batgirl and doesn't like her sister that much.

this is not following any batman storyline, this is my imagining of this universe.
