Romeo and Juliet computer game

I am a high school English teacher and I am wanting to use computer games to help teach kids about literature and understanding it. I want the game to be an RPG that follows the plot of Romeo and Juliet. I want it to start pretty easy, but become more difficult as the game progresses. This is to make sure it builds meaning for the game and retention of knowledge and a way to encourage my students to work with each other, read the play, or watch the movies
