Games are set to look much more realistic, computer-controlled characters will be more convincing and keen players will need to spend more to pursue their hobby, said a panel of experts gathered at a game makers conference in London. Some of experts believe that the improved look of games will raise players' expectations which will prove a burden for almost all game designers. Game makers will have to develop new skills and techniques to make the most of the opportunities offered by the new technologies. The problems and potential of the technology changes expected over the next five years was debated by game industry experts and veterans during the Game Designers Europe Conference. Jez San, head of Argonaut Games who started his own company when only 16, said the amount of polygons that a console could display per second improved roughly 100-fold every five years.
