8. You're The Villain
While Batman is a great character, you have to admit that most of the time, either in movies, comics or in video games, the villains are the ones who steal the show. They are the men and women who dare to challenge the Dark Knight, and sometimes they actually succeeds in causing some kind of damage to Batman. It would be very interesting to see how it feels to be the enemy of one of our greatest heroes. Think of the Riddler, for example. An app centered around you creating riddles and traps in order to defeat Batman and how you can achieve certain objectives in some amount of time would be really cool. Maybe doing something in which the more objectives you complete and more money you gain then your equipment will be much better. But why stop there? Why not making several of those centered on different characters? Maybe you can be Black Mask, trying to take control of Gotham City's underworld while dealing with other mobsters; another one in which you can play as Deathshot and you have to hunt down Batman; hell, why not creating one centered around the Joker? I think it would be great if we could see if we can outsmart Batman.
