GameMaker: Studio was among the first non-gaming software to be released on Steam three months ago - a tool for game development across all levels of ability, for ages 0-99. Or at least, from entry-level to wizened professional.
It arrived with the ability to upload your completed game onto the GameMaker portion of the Steam Workshop for others to play and critique, with the eventual goal of developers getting their game into the Steam store. To show the seriousness of their intent, they’re offering a $1000 bounty to the top rated game on the workshop.
Steam has started selling software as of yesterday, which is cool but of no direct consequence to PC gaming. Except, maybe it is. Amongst its first ranks is GameMaker: Studio, the all-over development tool used to build recent indie notables Spelunky and Gunpoint. Using GameMaker’s free version, indies will be able to develop and release games direct to Steam Workshop.
