Well in a world where free stuff/money gives a person/company a leg up it would appear that the practice of giving free keys for votes through the Project Greenlight portion of Steam is starting to draw some really pissed off or frustrated comments coming from the people at Valve. They fear that this type of practice, which is strictly vote yes for the game and get a free key puts Valve in a bad place as well as it apparently is making other Greenlight hopefuls in a strange positioning of not knowing if this is the new "it" thing to do now.
Of course Valve has come out and already stated that if this practice continues the whole selection process might take even longer and might be tougher to get through. To be honest, I think that that might not be that bad of an idea. Sure the vast majority of the games I've seen come through are marginal to excellent, but there are still those games that SHOULD NEVER have made it through that did.
Then again wasn't Valve going to do away with Prject Greenlight in its current iteration anyways? Wouldn't this just be the perfect excuse to completely shut it down for a while and make the system stronger and perhaps better for those who are actually trying to create something unique and awesome, instead of those trying to just sell there crap?
