On Steam there's the Greenlit section.
Only vote for what you want, don't vote for the rest.
However it's abused by developers and bundle makers in that the developers may for instance run a contest where you're supposed to vote it up to be part of it or the bundle makers promising Steam keys if the game is greenlit.
Hence you get votes for shit.
If it was more restrictive and shit wasn't let it that might had been a good thing.
Alternative is to put badges on all the titles where you put gold badges on actually good products played by many, silver on other good/decent products and nothing on the rest or something such.
