@kkslider5552000 Well my high school teachers didn't say that per say. It was more along the lines of "do not use Wikipedia as your only source". Wikipedia is fine for a starting point but it definitely isn't the end all (nothing is).
@Jeremyx7 Don't use that definition of "review", that's the verb definition. You want to use the noun version, if you want to make an argument on the definition of "review". Also, game reviews generally are not solely an overview of the game. Everyone out there uses different information; what you want to know does not necessarily pertain to anyone else. You cannot reasonably expect a reviewer to cover all bases, as quite simply it's not possible to, especially if they need to use their time for other reviews or have some other job or life out there.
