Metrics

Metrics, also known as Telemetry, are the tools Game Developers use to measure player behavior in their games. The way this is often achieved is by using hooks in the game's programming that sends data back to the developer.

Uses and Benefits
A well designed metric system can give the Game Developer very useful data during the playtesting during development and for making effective patches after the game is released.

What Metrics Don't Solve
Innovation. Metrics are a tool to help polish games, however there hasn't been a metric that led to a completely new gameplay experience.
