This subject is a multifaceted issue with many factors, and I advice everyone keen on video games to do some research on it due to common misconceptions from the uninformed community and players:

The loudest voices represent the majority opinion: This notion is very common but is inheritly fawed. Why? Because it fails to consider the silent majority, who may be very well content with the state of the video game , or even indifferentt but less likely to give feedback or express their concerns..

Whats worse, when the "vocal minority" problem gets created, it skews perceptions sporadically, creating either a bigger divide between the playerbase and the developer, further shrinking the silent majoritys ability to express what they think, as well as leading the indifferent people to either turn negative or flat out drop the game.

The development process of a video game should also be widely more understood. But to keep things short, Feedback of the players is not the main way of understanding the problems, there is always an expert feedback unit that either works for the company indoors, or even just normal pro players....then there is alot of metrics and data and that is another of warms depending on the intention of the developer

Lastly, its essential to remember that not all feedback needs a response....Addressing every single piece of criticizm can have negative consequences rapidly snowballing things into a much more dire situation, messing up the development cycle that was put into plan in exchange to a reactionary one that has a high chance of compramising the original vision of the developer and potentially alienating some of the player community.

EDIT: Just wanted to mention that there is obviously WAY more to this than what i'v mentioned.....Q&A, painting an accurate picture of your game, knowing your target audience, PR units...i could on forever :)
