Fun
The category pretty much tells it all. Is the game fun or is it a bore? Did I enjoy it or did I feel it was a chore? That is mostly what this category represents. This category tells you the main part of a video game, is it fun. There is no point playing a game if it isn't fun.

Story

Challenge
Challenge is a rating of if the game is not too easy or not too hard. Games do not have a good challenge factor if they are too easy or too hard.
