It seems to me that fanboys and fangirls who like a certain game that they know is flawed and yet defend it against all opposition sans any degree of logic associate other people's criticism of that game as a direct attack against them personally. This is because they associate some aspect of the game with an aspect of themselves. Also, I think spending money on games in this economy makes it important to choose your games carefully, so some people would rather pretend a game has no faults in order to justify their spending money rather than honestly analyzing it (something that perhaps should've been done before purchase).
