2. The computer games industry has grown phenomenally over the past 30 years and we have now reached the stage where many households have a games console. Games sell in huge numbers, for example Mario Kart Wii has sold over 21 million copies. These kinds of sales figures mean that the computer games industry is catching up with the film industry in size, and many IT professionals are attracted to work in the industry.

3. Computer games are categorised into genres. Similar to music genres or film genres, a computer game genre is a category of similar games which have common features, styles and objectives. Each genre tends to attract the same types of players. For example, first-person shooter (FPS) games are mostly played by males aged between 12 and 30, whereas brain training games tend to be played by females aged between 25 and 60.
