how many ppl actually go by gs;'s reviews?

i do, i go by gamespot, but i also go by ign and other websites, then i sum all the scores. (like gamerankings.com)

I use the review as a warning, but like many have said if you like the type of game you should still make a decision on whether you want to buy it. For example Call of Juarez is going to get a pretty low review, but I like all western games and I am probably going to buy it.

i go by gamespot's reviews a lot but not all the time because they can be wrong and make a game like crap with the review

when the game is actually good 

I actally think they are a great site for reviews. I trust them.

Not always with the score neceaasrily, but in there reviews, i find that they are very in depth, and they explain things very well. They actually say why they did/did not like them, and give reasons and examples. Becuase of that i can judge weather or not i will like a game. Like if they say the game is bad becuase there is a lot of monotonous leveling up, and slow progression, i can judge that by saing "well, i like level grinding, so i will liek this game".

So ya, i love there reviews, they give me a on of great info. 

i factor it into my decision, of if i want to get an old game i might look at the gamespot review.  i dont use ign that much, no particular reason i just like gamespot.  but some games i almost know that im goin to get, like graw 2, c&c3, gears, i dont even wait for the review i just go and get em
