If developers or publishers are interested in that they'll ask Steam to add that option.

That being said, I don't know that companies are that interested in the noise people who aren't interested in their product make. And a data point that some people don't like the genre, or art style, or whatever tells you what? That you can't please everyone? Already well known.

So I guess why do you think it would be a good data point? What do you imagine the user feed back will look like? How do you think devs and publishers should filter and consume that info?

It can depend on the volume of people ignoring a product. You could select a predefined reason or allow the user to write out a specific reason. With AI you could even have it collate a weekly report, sorting the general responses to performance issues, gameplay, characters, story etc.

Perhaps you could do the same thing with refunding the game and give those users a more weighted say.

You can just post it on their forum.

I like this idea but not even to share with the developer; I want a reminder for why I ignored a game.
