Successfully crowdfunded via Kickstarter and now available on Steam Early Access, Larian Studio's action RPG Divinity: Original Sin will also offer some powerful content creation tools.
Demonstrating the versatility of the Divinity Engine Toolkit, the developers have knocked together Cow Simulator 2014, a quick game mod that puts Divinity's livestock back into the driver's seat.
Cow Simulator 2014 is perhaps the finest cow simulation ever released. It serves as an example mod for would-be creators and permits users to play as a cow (even in co-op with up to 4 players) and complete a quest or fight in the arena.
In addition to deep customisability of the game's environments, dialogue and scripting, The Divinity Engine Toolkit boasts full Steam Workstop integration, with in-game mod management and 1-click exporting. According to the developers, it will be available Steam Early Access purchasers as soon as Valve hits "a magic button that will make the editor public".
