Monitoring performed by game testers is different from emotional criticism
It is a constructive process to improve the game, and strong language or insults are unnecessary

Testers must organize the reasons behind what users feel are “good points” and “concerns,” and communicate them in objective terms

Levels of objectivity

Game testers are the first users in the world to play the game
No game has succeeded by ignoring user feedback

If testers find themselves immersed in playing during testing,
the game is almost guaranteed to be a hit even before release (and the opposite is also true)
