The publishers made them. If you don't have an early review ready the second a game releases, nobody cares about your review. Publishers knew that and would blacklist anyone that gave them bad reviews. No early copies means no day one reviews.
So all that are left are places like IGN that will never give a score lower than 6/10 for the largest dog shit games in existence.
I have a bridge to sell you if you think grok is collecting the least amount of info.
