Tracking game metrics data is slowly becoming an industry standard for analyzing and improving games. Using insights from statistical analysis, games are becoming more adaptive and cater to individual experiences. Thus, biometric analysis is the latest trend to gather objective insight into player experience. Operating with game and player metric data becomes more important as game designers move from being classically rooted in the level design department to having to shift their attention towards procedural algorithms and programming that is responsible for analyzing player data. This talk will introduce the next generation of designing games based on statistical data analysis (game metrics, eye tracking and biofeedback) and discuss the challenges of these new and exciting technologies.
