I have previously spoken about unique games, which were something new at the time - see my article "There can be only one". It was KeyForge by Fantasy Flight Games and designed by Richard Garfield of Magic: The Gathering fame, which started this new way of making games. There is probably a better and longer description of the term, but in short, the term unique in this context describes games where every published copy is different in a number of ways. In KeyForge this is, for example, the name and logo, as well as the composition of the different cards, but different decks will still have some cards the same. I want to look at some aspects of unique game design in more detail to explore the concept.
Ever so often something new hits the tabletop game industry and when this happens, it is always hard to say if it is just a flash in the pan or a new breakthrough that will turn out to be a game changer. However, I will stick my head out and make a prediction - and be happy to swallow my hat, if I turn out to be wrong.
