hmm well I found the demo on 1 of the magazine dvd's, so I tried it .... graphically it is way better then DS1, and even though I played for an hour or 2, it was fun, but as Shyon mentioned, I have a feeling too that it will become as boring as the first 1, which I never finished.
I just got sick and tired of following that spiral path up the mountain, since the RPG element is sadly lacking the quest in DS2 seems to be slightly more advanced and rpg like then DS1, but like I said (and shyon mentioned) it will become boring of that I am reasonably sure.
So to conclude, this is at it's best an Adventure Game, best suited to those who like the Hack & Slash variety, but do not even think that this is an RPG!
