In the industry, you're often focused on a specific genre of game, not thinking about the broad spectrum of games as a whole. So perhaps it takes a student's eye to spot larger industry trends.
Such it was today in class, when my Game Design students came to the conclusion that you could make a "kart racing" game for any IP, any license at all... while still respecting the original story. We were unable to find an exception. It would seem to be an entirely generic genre.
