Great RPG experience. New ruleset simulation (5e) is pretty good. Engine looks like it can have a lot of good use for many campaigns. I don't like the user interface for moving/camera rotation seems cludgy. Camera height could be better and should be able to rotate & move camera all with the mouse opposed to mouse + wasd. Item and object interaction items should have better highlights (they are hard to spot as scenes are very detailed). Engine needs some optimization, high cpu usage. If you like RPG games buy it.
Couldn't give any real comment on storyline. I tried playing the game several times but the user interface (on PC) is just so bad it was like going back 15 years. Got so pissed off about it that to save myself stress it was easier to just delete the friggen thing. Witcher 1 was much better and even then it left a lot to be desired. I think this is more for 'twitch' console gamers but even then perhaps only if you were an epileptic.
