I don't want video game recommendations from someone that wants to sell me a video game, because they have a financial incentive to sell me a $60 game that I'll like instead of a $10 game that I'll love. No, I would much rather trust the opinions of people who have bought and played the game. I want to know if 99%, or 90%, or 65% of players gave it a good recommendation.

Long-time Netflix subscribers might be having déjà vu right now. Old Netflix had a ratings system, and users could filter content by average rating and see the top-rated movies and shows. Netflix later replaced that system with a recommendation engine. Not only does the recommendation engine not get my taste right, but it sure seems to recommend to me a lot of Netflix Originals.
