I dont think so... If you go on Amazon.com they've had reviews up on there for weeks, maybe its because people over here haven't actually managed to get early copies of it yet or they just haven't posted the reviews yet, but seriously go check the Amazon.com site and you will see alot of early reviews that are poorly written
US had an early releace but only by 3 days, so most of them cant be authentic.
its sad that a game cant run on its own metits or flaws because fanboys allywas rate them high, if there good or bad or evan not out. its one of the reasons i dont trust reviwers anymore, that and every major title was given ether 10/10 or 9/10 for being know not good. Take GTA4 for instence it was prased over and over again for doing what GTA 3 did in HD (almost 10 years ealyer) ignoring its sequils and improvements. the game can be fun but i would rate it a 7/10 because of the mass content it missed compared to its predicesor San Andreass.
