Every summer brings a crush of gaming conventions. Few in China draw as much attention as ChinaJoy, which has been running for more than two decades.

China’s gaming industry has seen two major trends in recent years. One is the rise of homegrown games, particularly indie titles and AAA productions. The other is artificial intelligence’s advance into nearly every stage of game development, and increasingly into the player experience itself.

Improving game content has long been a theme at ChinaJoy. Over the past two years, however, AI has begun changing not only what is shown at the event, but also how games are made, distributed, and operated.

At last year’s ChinaJoy, the debate centered on whether AI could actually make games. This year, the event’s theme shifted toward the idea of playing alongside AI.

During the four days of ChinaJoy, 36Kr visited every exhibition hall and found that companies differed widely in how they interpreted and put into practice the idea of incorporating AI.
