I played FOV the first time 150 hours in total.
I tryed to solve quests in every possible way.
I explored quite thouroughly (like the grave in broken valley that has also a solution to get something nice...... for example)

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.

I'm pretty sure now that the time showed is indeed the gameplay time. There's been times when I haven't spoken to anyone and then when I go and speak to someone, the counter has a few hours gap so it must be based on gameplay.

In any case I've noted that my playthrough on nightmare difficulty is taking longer. The counter says 27 hours and I'm pretty sure it'll be around 33 hours when I finish Ego.

Hmm, very interesting Demonic
I gonna have a second look to the showed "amount of time" ...

When I last checked, I was up to 332 hours played on DKS. The first 180 of those were for my first three playthroughs of the game, the rest was for my work on the Let's Play I did.
