TOPIC: Divinity 2 GM mode?

Hey anyone had any experience of Divinity 2 Original Sin and it's GM mode? Basically lets you use the games engine to run your own adventure as a DM crafting NPC's and maps etc while the players can play classes from the game. Looks interesting but not done it myself. The fact these guys are making Baldurs gate means we could in a few years have the same sort of setup for 5E as well.

Video of a game ran on it by Matt Mercer if anyone interested or has the game and wants to give it a go.
