Valve will allow people to monetize their creations through Steam Workshop.
Details are now on the Steam workshop page: https://steamcommunity.com/workshop/
When I first saw this, I thought, "Cool!" They've had the ability on Skyrim Nexus for a while to pay people, and to have that same ability on Steam seemed like a cool idea. After trying the modding, I know how much work these people put into this. It could start a whole renaissance!
But whenever you put the idea of not free into an arena where free existed, people get upset.
Personally, I use Patreon a lot, to support micro projects for people that I think should be supported, and that release things that I use, and I love it.
The one thing that is still very bleh is the amount that they take. For providing a service that allows delivery, the margins should be 15% on the outside, IMO.
But the idea is very cool and very needed IMO. The only way to monetize these very useful skills shouldn't be by begging or hoping that you get picked up by a game company.
