So it seems that I gonna love both games, each with their own nice things !
So far I love more Divinity II, but that's because I play that game many many more hours ... Divinity II has already win my heart since the start of year 2011 .
Dark Souls is only recently bought and a little bit explored (I think I'm still in the tutorial zone !) ... so far creepy, but fun and 1 time almost death because of some Giant big enemy I have escaped in time !
