Apparently (as in, according to the conversation log) 30 hours for ED and 10 for FoV. Strange, I thought it was longer than that: if I'd been asked without checking, I'd have said up to twice as much! I think I padded it out a bit with my adventure into modding the game a bit (I mean in addition to the time I mentioned), and I imagine in my first play-through I probably played a bit longer as I explored everywhere probably multiple times. Even though there was still stuff I missed, as it turns out.

J'aime le fromage.
