Yeah, it’s a bit of a cautionary tale of the depth and clout of business amidst the entertainment of games journalism. As Reaxxion summed it up:

The firing of Jeff Gerstmann was a giant bomb in gaming journalism’s history. Though this event happened a long time ago, it’s important for the gaming community to remember what happened to Jeff Gerstmann in 2007. Gerstmann could’ve easily avoided all that trouble and gave the game 7.5 score and nobody would bat an eye because he is Jeff Gearstmann. Instead, he gave the game 6.0 and lost his job as a result.
