I tend to listen to Yahtzee for certain games, because he does bring up excellent points on things of the game.
With that said, you cannot base your ideas solely on his, because you might be into games he doesn?t like, because we all have our own opinion and tastes. If we didn?t we would all be stuck playing the same type of videogame over and over again, without the chance of any cool and new innovative ideas coming to surface.
I happen to like hearing Yahtzee?s reviews because they tend to say things some other reviews won?t say, while keeping me entertained. Now, that doesn?t mean I am a mindless zombie following another persons words. What I do is I take what he has to say and listen to any major points that he brings up. If they were small points that I might overlook and the game does look like a good game overall, then I would probably still get it. If, however, he brings up something that shines a light on a big design flaw I would probably stay away from it, because I know there are other games out there and I do not want to invest solely on a game that would be bad.
He is going to point out the bad stuff, because that is his job. What you have to do is look at the stuff he says and see if you might overlook it, or if the rest of the game is good enough for the flaws to not matter. He also points out good stuff to and does a rundown of what the game is about. Often, you will notice he does show that some games have really good aspects. You just do not notice them right away because you are too distracted by the negative comments. If you listen though, he does try to show most of the points so you do get a good idea of what the game is about.
Yahtzee isn?t just there to poke fun joke. His reviews are to explain a game so you can know a little about it before you drop your life savings into the pockets of videogame companies. It is always nice to get a second opinion from someone who knows what he is talking about, and Yahtzee is not limited to what he can say so you know what he says is how he feels.
At most, you can always just rent the game and see if you like the game yourself. It is not the review writers? job to form your opinion, unless you are a reviewer, which in this case I might ask why you need to know others opinions if you already have a square mind of your own. Really, reviews are there to give a game overview so you don?t waste your money.
I would take to heart what the review says, but I would not make it my only opinion. I would still go and see if I might like it or not with a demo, or at most read a second review.
