I know this will be lost almost immediately if I don't use big text, so I hope I don't get put on probation for doing so.
[HEADING=1]Yahtzee is not a reviewer, he is a critic.[/HEADING]
And yes, there is a difference. A reviewer gives his general impression over a particular book/movie/game, rather than going into intricacies and doesn't analyze all the technical details of the material.
A critic, on the other hand, goes out of his way to do what a reviewer doesn't. His job is to analyze the work from a technical perspective, hence why Yahtzee places much more importance on specific points about the game, rather than what his overall impression is. It is his JOB to find all the faults in the work, regardless of whether or not he liked it (hell, I'm fairly sure he said this himself in one of his episodes).
Granted, I'm not sure why I'm really defending him seeing as he doesn't know or care who I am.
