Are you the 3.5 percent?
The Global Gameplay Stats for the Steam version of Divinity: Original Sin revealed that only 3.5 percent of players "totally, completely, and utterly finished the game."[1]
It's estimated that it takes approximately 80-90 hours to totally, completely, and utterly finish Divinity: Original Sin.
Please note that players who didn't launch Divinity: Original Sin online before passing that game offline aren't factored into Steam's Global Gameplay Stats.
