Here is a quote from the book 21st Century Game Design, by Chris Bateman and Richard Boom:
"The obvious candidates for such originality (from a publisher's perspective) are licensed games, ironically the traditional reserve of the most conservative of designs. Because these games already have a certain expectation of audience from the appeal of the license itself, they are great opportunities to pursue originality. However, this is only the case when the license materials suggest a new form of gameplay."
That's pretty much the point I was trying to make (just written previously and better)
The Godfather would have been a right choice, then. Batman, not so much.
