Methods for game user research: studying player behavior to enhance game design.

The emerging field of game user research (GUR) investigates interaction between players and games and the surrounding context of play. Game user researchers have explored methods from, for example, human-computer interaction, psychology, interaction design, media studies, and the social sciences. They've extended and modified these methods for different types of digital games, such as social games, casual games, and serious games. This article describes several current GUR methods. A case study illustrates two specific methods: think-aloud and heuristics.
