Factorio Forums

Most of you might have heard by now about the Games in Development initiative by GOG Galaxy. It is basically like Steam Greenlight, but curated and checked. Given the aesthetics and gameplay of Factorio, I think it would feel right at home on GOG and its playerbase. Might be worth something looking into for the devs?

They are windows only ?

Also available for Mac OS X and soon for Linus as per their own page.
Regardless, even though Linux is not supported yet (but will be) (soon tm) it gives great exposure to the game.
