Well, if I were you, I'd cut out everything from (roughly) "There are several major kinds of game buyers..." to "... “Pokemon Black? Yes, please.”", and replace the next paragraph with something like:
"Few people are influenced by box art. They make purchasing choices based upon the reputation of a product (for example, they might make decisions based on the advice of friends or on the recommendation of a reviewer), because it is a part of a trusted brand (for example, if the product is a sequel to a favourite game, features familiar characters, was created by a respected designer, or released by a favoured publisher), or because it is familiar (for example, in terms of genre or gameplay mechanics.)"
However, bear in mind that if you are going to make sweeping generalisations then you need to provide evidence to support them - evidence and references help seperate facts from opinions.
I hope this helps.
