Some games are absolute crap.
They may be horrible quality, horribly glitched, or just horrible period.
When you find one, report it here. Argue it amongst yourselves.
If at least three of you agree it needs to die a vote can be created with the options (remove, keep, no opinion), with the URL of the offending game so others can test it out, and if after a week the overwhelming consensus is the game is crap, it will be removed.
Games that are reported as inappropriate content, or violating the rules in some way may be removed sooner.
