O, if that is truth that Dark Souls is more easy than Divinity II on nightmare difficulty .... ?
But yes I played almost the whole part of Ego Draconis on nightmare and now playing FoV part also on nightmare mode.
Dark Souls will be more difficult in the beginning because of the controls are so different from Divinity II, so I'm now clumsy with the fighting controls in DS

...
Also the save game system is different ! In DS you've only 1 save per character, so EACH action is always irreversible !
But in some way I play Divinity II in the same way (without reloads), but I make more than 1 save game so in case of a 'bug' ... So I really hope Dark Souls have no gamebreaking bug !! Otherwise they do a big mistake making it that way!
