Use game reviews to guide your decision but not make if for you
Video games are very fanbase driven. Not a sports fan, well then the latest Madden no matter how fantastic won't appeal. Not into first person shooting games, well forget about Halo and Call of Duty. Fact is even bad games get bought and enjoyed by small pockets of fans. There's a reason that the very bad controlling Dragon Ball GT: Final Bout on PlayStation was selling for into the $300's on eBay years ago. A fanbase makes even bad games successful. For this reason game reviews on websites and in magazines need to be approached with a huge grain of salt. No matter how bad, or good, a game may be it may not appeal to everyone. A review is an impression folks, an opinion of that one reviewer. Sites like Metacritic do a good job of gathering a lot of opinions and articles like Gaming Blogs You Didn't Know Existed give a good recap of areas and sites to be checked for such opinions.
Not every gamer is the same nor is every game review so be careful with your purchase. Be smart, do research and rent, find out what games you enjoy and which sites enjoy the same games then trust them. Game reviews are just opinion, but then again that’s just my opinion.
