To ring in 2011, here is a list of frontiers in game design. This list is not complete, but it gives some hint at the vast breadth of games still left to be designed. If you come across someone who claims that all games have already been designed or that game design is a solved problem, show them this list. And then challenge them to stop fiddling about with over-exploited games from decades past and make something new and wonderful that will change the world. Go west, young man.
