You should play it, its second half is better than the first.
What I meant with "a little like the first System Shock but not so much" is that I found SS1 amazing in many aspects, but most of its gameplay is as a shooter, and as such it's kind of terrible. (I think we already had this discussion.)
SS2 is not the best shooter there is, specially in melee, which you're supposed to use quite a lot; but it's good enough. And overall it's an amazing game.
