Never played Dark Souls.
I really love the original Witcher, and Witcher 2 is great too.
DA: Origins is nothing short of outstanding.
I thought Human Revolution was a complete mess, but most people disagree with me there.
Mass Effect is a great RPG, and ME2 is an unforgettable experience, though not really much of an RPG.
KOTOR is extremely dated, so approach with caution.
I would recommend Witcher first, since it has a sequel which is already out and actually a great RPG in its own right (unlike DA2 and ME2).
