Like Gabe Newell said: "We want greenlight to 'go away'..."
I guess greenlight ->as barrier<- is fading away and becoming more of a prioritizing tool for Valve and for us developers which I think is a good thing. Since some day everybody will be able to publish games via Steam without any barriers. I guess Valve are just slowly opening up the platform to test their discovery tools and find ways to let quality content shine even if there is a great amount of content. (Reviews/Curators/Custom Stores ... they are trying a lot if you look close)
So in hindsight I thing Valve is doing a pretty good job in taking away the heavy impact by opening up the platform slowly if you know what I mean. And I think its time to look at Greenlight more as THE tool it was meant to be from the beginning (but was massively misinterpreted) - It's a tool to measure public interest in a game.
So trying to 'cheat' the system by offering free keys and stuff to get through the system fast is useless - in the end that only takes developers longer to find out if their work gets received by the steam audience as intended.
I come to this conclusion since my second Greenlight project only took less then 2 Months to get greenlit and I see a lot more games coming through the gates than a few years ago.
What's your opinion on this?
My impression is that Greenlight can already serve to let the games through that people are interested in. This can be measured via the Yes/No interest and the number of total votes.
I guess, by free keys, you are referring to those services that offer you to get your game greenlit (i.e. help you with votes) in exchange for you giving free copies for their promotions? Is the number of games doing that significant?
If the current system wouldn't be in place, what could take it's place? Would it become similar to one of those online portals (e.g. Newgrounds) where there's still an initial rating based voting but if the game passes that, then it can "stay". Sure, there are daily, weekly, best as well as front page as well searching for games based on ratings. So, if your game is "good" then it should still stand out but I wonder about game dilution in a general sense.
