Let's face it, one glance at the charts will show you that the public isn't too fussed about originality. The public wants first-person shooters, fitness games and the next FIFA or Madden. It doesn't want LittleBigPlanet (despite Stephen Fry), couldn't give a damn about Okami despite all our best efforts, and thinks Rez HD is a sleep disorder you get from those newfangled tellies.
But while some games are unoriginal to the point of lawsuits (Simpson's Road Rage, how do you plead?), there is a lot to be said for a brilliantly-made game that adds little genuinely new to the genre. In fact, some of the best games of the past 12 months have been made up of little more than old ideas cleverly repackaged to create something wonderful.
