Do you think they are? I think so
Take VGA for example. they always nominate popular games over quality games. for example last year skyrim won GOTY and True GOTY Deus Ex was not even nominated. they nominate Dragon age 2 over witcher 2. they havenot nominate shogun 2 for best RTS or even best PC game
Back in 2010. they claim Halo Reach and COD black OPS are highlight of FPS of 2010 when in reality Stalker Call of Pripyat and Metro 2033 were.
They have not even nominate Stalker Call of Pripyat for best FPS but it was clear winner. MUCH better than Garbage like Halo Reach and Black OPS.
Its all money talks. Its all corrupt
