I cant see how for me Demons could even come close if it was not open world.
To see a game bring back walking everywhere... was INCREDIBLE. In todays world of slack ass lazy gamers who have a tantrum if they cant fast travel absolutely everywhere (bloody skyrim -_-)
Of course having said that I am not that much better, now that I have been spoiled by it I too enjoy being able to fast travel in most games but in Dark Souls they did this so well, in that as soon as u start to get cocky coz u have passed through an area a few times, casually fighting mobs they will suddenly start to overwhelm you all of the sudden coz u let your guard down.
Sadly I never played Demons but will definitely get it and play it just because Dark Souls immediately became one of my favourite all time games, I have a feeling I wont like it nearly as much as I started in the wrong order.
