Divinity: Original Sin 2 is a really good game (we selected it as our game of the year for 2017, remember, and we can be pretty picky about these things), but apparently it's not quite good enough. Developer Larian Studios is working on a Definitive Edition version of the game that's set to come out in August for the Xbox One and PlayStation 4, and owners of the original on PC will get it as a free upgrade. 

Larian revealed the Definitive Edition yesterday with a video introducing Feedback Billy, a new, more interactive system for collecting feedback on the game. The video only mentions the Xbox One version of the game (which will be available tomorrow via Xbox Game Preview), but over on Facebook the studio said that the updated release will be coming to PC as well.
