With Valve's new Steam Greenlight initiative, they're attempting to democratize the process of getting a game approved for sale on Steam (a process that was previously opaque and notoriously difficult.) Many people stillaren't happywith the service's $100 fee, but despite the anger the service's first titles have just been approved.
The first games to be approved for release will be: Black Mesa, Cry of Fear, Dream, Heroes & Generals, Kenshi, McPixel, No More Room in Hell, Project Zomboid, Routine, and Towns.
"The Steam community rallied around these titles and made them the clear choice for the first set of titles to launch out of Greenlight," said a Valve representative today in a press release. "Since launch, hundreds of titles have been submitted, with more coming in every day. We expect to be announcing more titles coming to Steam via Greenlight soon."
There are still many popular titles which have not received the greenlight just yet though. Notably, Octodad: Dadliest Catch is still lingering along with the Stanley Parable: HD Remix. There's also a game called Dino Storm which features cowboys with sci-fi weaponry riding dinosaurs. Which almost certainly deserves your upvote.
