2006: Dwarf Fortress
It is important, when contemplating Dwarf Fortress, to realise a couple of things.<p>Firstly, and most obviously, the game is clearly some sort of work of art. The exact nature of the art is a bit difficult to pin down - certainly isn't an exercise in graphics and the plot is inconsistent between playthroughs - but nevertheless.<p>The second thing to observe is it appears to be a life's work. A lifetime has not actually passed, but still there is a singleminded dedication here that is unusual.<p>Thirdly, it is impossible for this sort of art to be a true lifetimes work because computers havn't been powerful enough to do this sort of thing for the full 50 years it takes to dedicate a life to one thing. Furthermore, not enough people have been exposed to computers yet.<p>If humanity survives to 2121, there are going to be some amazing games. Gamemakers like Tarn, possible multiple generations of gamemakers, polishing these things will have some remarkable outcomes. I am glad to be around now at the birth of computing, but it is all too easy to envy the people who will be young in the 22nd century.
