I dont think your maths are right.
Let me explain.
...Of Illusion = Nostalgia, sells to old fans
Epic + Mickey = has the Mickey name in big letters, sells well to children, children loved Epic Mickey
Epic Mickey + of Illusion = Nostalgia fans, kid fans = $$$
Now add to that IF the game is good it will sell even better and pleases all types of fans for a next game.
Now there, here you have your formulas corrected. Have a nice day.
