Glenn Entis, CTO at EA, said at Siggraph that games need to become more realistic:
Game worlds must not just look lifelike, he said, they must also react in a realistic manner too. Tools that let players create content were also becoming important, hew added. During his speech, Mr. Entis warned against assuming that games which look lifelike automatically take on the characteristics of the real world.
It is especially important to design human characters. Special attention should be paid to characters animation, as they should not only look real, but also move realistically: you can hardly impress a contemporary gaming fan with a large number of polygons in this or that model. However, high-quality animation of a model with high-polygon count is not enough to ensure realism of non-player characters. Mr. Entis believes that they need AI, smart enough to make the player forget for a second there that he or she is dealing with a computer-controller character.
