Unlike movie awards which can be given to movies that made no money or arent even in English, video game awards are mostly heavy hitting big sellers unless it's the indie award.
Video games makers and game sites and promoters are too handcuffed to each for the industry to be less biased. Just look at Pope Jr himself with his doritos and mountain dew. It was so thick in money it's like the guy was the VP of Marketing at Pepsi. Too much free product, preview copies and banner ad revenue floating around. Just look at the Jeff Gertsman Kane & Lynch debacle. On the other hand, how often have you ever seen a movie reviewer give a bad score and suddenly he and his site (or newspaper) get reprimanded by the sponsor and the guy gets fired to boot? Probably never. Even if a movie studio threatened pulling money, it sure looks like no movie critic or site cares to cave in because bad movie ratings are just as common now as 40 years ago.
The 6-10 scoring system in gaming is already a bad sign. Movies since the beginning of time can still get scores ranging from 1-5 stars. Some might even get 0 stars. At some point (probably the early 2000s?), game review scores all amped up when in the 80s and 90s you got more shitty review scores that can actually be under 50%.
