At the Game Developers Conference, Valve has formally announced the Source 2 engine and that it would be free for content developers. At the same time, they committed to releasing a version of it that is compatible with Vulkan, the graphics API from the Khronos Group that we have been talking about a lot over the last couple of days. Of course though, free can mean many things. As it turns out, there is one string attached: the game must be made available on Steam at launch. It can be available elsewhere too, but Steam must be one of the launch retailers.
I do wonder what will happen if someone makes a title that Steam refuses to publish. Of course, the natural thought is “What if Valve refuses to publish for content reasons?” That is an interesting thought, and maturity is one area that many other engines (like Unreal) do not restrict, but it is not the only concern (and Gabe Newell is quite laissez-faire with his — albeit loosely defined — content guidelines). What if your content simply does not make it on Steam? For instance, with is someone creates a title in Source 2 and has a failed attempt at Greenlight because it was unpopular? Are you then unable to publish your content through alternative channels, too? This seems like something that Valve will need to provide a little clarification on.
Try as I might, I could not find a release date for Source 2, however. It will arrive when it does.
