After going through the development cycle for years, game testers grow tired of the game they work on and often times no longer have the desire to play the game.
Joe: "Hey you want to play this new game that came out? Its awesome"
Tester: "No thanks, I have Tester Game Fatigue. Spending 3 years on every little detail for long hours has sapped my desire in playing the game."
