Well, my Steam counter marked 106 in my first playthrough. I was eager to play Divinity 2, so I tried to play it smoothtly and exploring every corner ^_^ I'm not sure, though, how much time I spent with "ego draconis" part, compared to FoV.
Right now, I'm on my second playthrough with higher difficulty and a new set of skills (triying to make a versatile warrior). The counter marks 150 hours -only Aleroth and the hall of echoes left.
