For convenience, let me quote parts of this article:
For example, a consumer cannot decide between two popular video game consoles, but in the end decides to purchase the one that many of their peers also own. After purchasing it, they may find few games for their console worth purchasing, and more for the console they did not purchase. However, they do not wish to feel they made the wrong decision, and so will attempt to convince themselves, and their peers, that their original choice was the correct one, and the consumer's opinion is better than everyone's opinion, i.e. using sour grapes arguments
The above should help you navigate VGChartz quite nicely.
