Anything that isn't on Xbox gets rated lower.
Anything on Xbox that is an FPS that isn't Call of Duty or Halo gets rated lower.
Anything relatively fun gets rated lower.
But if it's Call of Duty on Xbox, it gets rated near perfect scores. And IGN vowed to "never give out perfect scores. No game is perfect." Fucking assholes.
Most of the "reviews" are bias as Hell, and the games always get rated depending on what console it's on and how much the company that owns the game they're "reviewing" bribes them.
A perfect example for IGN's shitty-ness are their "reviews" for the new Madden NFL games. All of them are rated high-as-fuck even though Madden games are the same bullshit every year, just with different character designs.
IGN has never, and will never, write a good review that isn't about a game made by their gods EA, Activision, and Microsoft.
Did I mention they were also owned by a news broadcast? Something like FOX News? That would make a lot a sense.
Plus, it is owned by News Corporation (Does FOX News and Rupert Murdoch ring a bell?)
Person: I'd like to be a reviewer for video games!
IGN employee: Do you love Xbox 360 and hate the PS3?
IGN employee: Do you love Call of duty and think all other FPS's suck ass!
IGN employee: You're hired!
