I agree 100% with @mattornb about people not wanting to buy stuff because they're uncertain about quality - the main reason I hesitate to buy things is because I'm uncertain of the quality, and even if it's a monetary loss I could live with even if it's so crap I won't ever play/use it, I still feel really uncomfortable buying something I know nothing at all about. When I'm on the fence to buy a game, I don't check out reviews. I check out Let's Plays or trailers that show gameplay footage (preferably the former), because I want to judge if it's good or not by myself.
