The post-lunch sessions of this conference constitute a mini-conference on computer games and the law. It is opened by Greg Lane of the Brisbane-based games developer Auran, responsible for titles such as Dark Reign and Trainz. The computer games industry is significantly large - twice the size of the movie industry, and growing twice as fast. In its multimedia inputs it's also a classic example for creative industries production, which involves massively interdisciplinary inputs into its IP 'asset creation', as Greg puts it. Interestingly, too, games are increasingly involving user co-production or co-creation. This is the case with Trainz, a train simulator which enables its users to produce rolling stock models, physical environments, and action scenarios to be used in the game - and interestingly more content was produced by users for Trainz (which sold some 3-400,000 copies) than for the only competitor project by Microsoft, which sold ten times as much, due to Microsoft's reluctance to engage fully with its users.
