Those who submitted false entries on Greenlight have ruined it for everyone else.
A few days ago, Valve announced that Steam Greenlight, a community-driven effort to streamline the approval process for indie games to make it onto Steam, was finally live. The developer was probably too optimistic about Greenlight to see the hazards of hosting open submissions with relatively few stipulations. Within a matter of hours, Greenlight was flooded with fake content, including the ever-elusive sequel to Half-Life 2.
In order to beat back the tide of false submissions, Valve's tweaking Steam Greenlight's policies a bit. Now, developers will have to pay a $100 fee, which Valve will donate to the charity Child's Play, in order to submit an entry onto Greenlight. Considering the costs to develop a game, $100 isn't wildly expensive for an indie developer to pay, especially when it comes with advertising to the Steam community. The fee will also deter those submitting Half-Life 3 as a joke.
It's sad to see that those who decided to abuse a useful free service have ruined it for legitimate indie developers looking to get their content onto Greenlight. $100 isn't a heavy price to pay, but it's quite a bit heftier than free.
