Ever since the invention of the computer, man has feared 'the machine' and its ability to think. But a computer's unique computational power has also led to the development of games that are unpredictable, intelligent and malleable. Games like SimCity and Civilization simulate entire worlds and let players experiment with cause and effect. As the 1990s dawned, global turmoil forced gamers to find solace in the world of videogames - a virtual world that offered control at a time when the real world seemed dangerously out of control. Now, videogames have become tools for learning and creative expression.
