During the Game Developers Conference, Firaxis Director of Creative Development Sid Meier gave a fascinating keynote speech in which he described the impact that player psychology has on his game design process, and how other developers can learn from that.

Following the keynote, IndustryGamers had the privilege of sitting down with Meier for an in-depth talk. The web site discussed psychology, morals in video games, the Civilization Network (which will debut on the Facebook social network as a game that friends can play with each other), the booming social games sector and more. Here’s the full Q&A at Industry Gamers.
