Look at this:
https://steamcommunity.com/greenlight/
Basicly it says anyone can put his game on a voting list called Steam Greenlight. Users will then vote for it to get it on Steam or not. The game doesn’t have to be finished to be on Greenlight. The service starts at August.
If the games posted on Greenlight can be free to play there is no restriciton for Black Mesa to be put on Steam.
Yes, yes, this is good. If they could tie it into their release promotion then Black Mesa would most likely make it.
Black Mesa will probably blow the service away on first day seeing how we reached the 20.000 fb likes so fast.
Git off yer ass n’ post a link fee us ta be votin’
The service won’t be available until the end of August.
But one thing on that page troubles me:
Does that mean that Black Mesa would not be accepted?
Far as I can tell Black Mesa seems to fall under the Fair Use clause, from what I gather everything was made from scratch and the only assets used belonging to Valve where apart of the SDK. Personally, I don’t think Valve would invoke their legal remedies at this point, they’ve known about the project for years. (This is my own opinion, it may be incorrect)
So, I’d imagine the mod would be completely allowed on Steam Greenlight. Wonder what the developers will think of it. That being said having the mod on Steam would alleviate any sort of distribution issues that could arise at release.
I know they won’t invoke legal remedies against Black Mesa (Valve knows about this mod and the only thing that they wanted changed, as far as I know, is that they didn’t want it to be called “Black Mesa Source”), but since Black Mesa does use Valve’s intellectual property, I don’t know if it would be greenlit or not.
Greenlight is primarily intended for commercial products, AFAIK
We know that BM won’t get sued by Valve, but they might get sued by Sierra. 
If only Sierra still existed… poor folks got eaten by Vivendi along with Activision, and Blizzard, who merged into Activision Blizzard back in 2008. I’m sure their “rights” to Half-Life are a mere memory. But I imagine your being sarcastic am I right? 
o jeah
Anyway… I bet BM will get voted the shit out of, to get into Greenlight, and that Valve expected it to happen all along.
Loving the way STEAM is integrating the community’s projects into the network.
First good new thread I’ve seen around here in AGES! Good job!
–
As far as the intellectual property goes, Sierra was just the publisher/distributor, Valve still owns the content.
Valve has known about the project for YEARS, so we can safely assume they are okay with it existing. Thus I see no reason why it couldn’t get accepted to Greenlight.
However, I feel like Valve will add it to Steam regardless because the quality of this thing is going to be insane. Don’t need a public vote to tell them that. 
It is, and the service already starts in August, which will probably not be too late for the BM release 
I vote for the Dev’s to go for it,
So’s I can put in my vote for it…
(bad poetry at it’s best)
VALVe knows so much about the project, they have actually set up the red line between VALVe HQ and Raminator, so whenever problem occurs Gabe can just have a nice friendly chat with Ram. If that doesn’t work, Gabe shows his knife collection… ._.
But yeah, the idea of the Greenlight is very good. You really think that there would be a game that would be more popularly voted than Black Mesa? I really can’t think of anything like that except maybe the Half Life 3/Episode 3…
This is excellent if it works the way I suspect.
Would these games be possible to be released on steam in the future?:
Downloading Black Mesa on Steam on a hot summer night…i hope this year dreams will come finally true
No. Only if the owners of the game allow it. You can’t post a game you don’t own personally. If you do, your submission may be deleted.
No because both of those are exclusive to Origin, its not up to Valve to put it on Steam, its up to EA to Allow it.
Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
