Gamespot's reviews have been degrading since before the Jeff debacle. In the Post-Jeff world of Gamespot, the reviews are even worse. I used to use Gamespot's reviews as one of many ways to determine if I should look more into a game I was unsure of. No more. I'll give you two perfect examples about how crappy Gamespot's reviews are now:
Army of Two. Why was this review so bad? It wasn't a review so much as it was a rant about how bad PMCs and mercenaries are. The writer of the review takes every opportunity to rag on about how evil and corrupt mercenaries are. I don't fucking CARE about your political or moral views; just tell me if the game is worth my time. It doesn't matter that the game itself is pretty underwhelming, the fact that the writer ranted about his personal views on PMCs and TOOK OFF POINTS because of it proves that this jackhole shouldn't be reviewing anything, games or not.
Universe at War. Firstly, the review was about two weeks late. Secondly, you could tell that the writer just played a few skirmish maps and wrote his review. It is sloppy, and the writer shows that he knows absolute jack shit about the game. He complains about the game lacking certain features standard to the RTS genre, even though Universe at War HAS these features. He just didn't take the time to learn all the basics of how to play the game. So when people pointed this out, what did he do? Did he re-review it, taking into account the fact that he took points off because he is too ignorant to learn the game? No, he just edited these parts out and replace it with things he pulled out his ass, like "bad controls." Things he didn't complain about the first time.
Not to mention the fact that, unless the game is really hyped, expect the review two-ten weeks after release. Hell, Gamespot never reviewed the PC version of Frontlines, and that came out in February. Actually, pretty much every game that came out in February-March 2008 didn't get reviewed until late April or early May.
Bottom line: Gamespot has zero integrity as far as I'm concerned. I still use the site, but only to track games, blog, and participate in forums and unions.
