I remember there was something mentioned awhile back about user-moderated store fronts. Combine that with the other crowd-sourced tools that are being added to Steam and Valve just might find a formula for surfacing the good stuff.
_"So the right way to do that is to make Steam essentially a network API that anyone can call. Essentially, it's like, anyone can use Steam as a sort of a distribution and replication mechanism," said Newell.
"It's not us making a decision about what should or shouldn't be available. It's just, you want to use this distribution facility? It's there. And customers decide which things actually end up being pulled through. So Steam should stop being a curated process and start becoming a networking API."
"The stores instead should become user-generated content. If a user can create his own store -- essentially add an editorial perspective and content on top of the purchase process -- then we've created a mechanism where everybody, in the same way we've seen a huge upsurge of user-generated content with hats, we think that there's a lot of aggregate value that can be created by allowing people to create stores."_
I already look at the user reviews and Steam community discussions before I buy an un-known game. Some of it is just loud-mouth trolls and general complainers but you can sift through it and get a feel for the quality of a game. If you could find a curated storefront by people you trust and who share your tastes that'd be even better. Incentivise those curators with a little bit of the profits and they'll be motivated, too.
