you have to understand that people here are fanboys.
they use review score as ammo for their fanboy arguments.
Most logical people know that 7/10 for a game genre they like to play is better than 10/10 for a game genre they hate.
For example...as far as my prefferences are concerned, 7/10 Silent hill game is >>>>>>>>>>> 10/10 Final Fantasy game
But you can't package personal prefferences as fanboy arguments so we pretend reviews are be all end all of gaming.
