Don't forget some of the worst voice acting EVER!
I actually didn't mind the gameplay. It did take some getting used to though. And the underlying story and world was actually quite interesting.... enough to keep me sitting through all of that horrid voice acting.
Actually, the voice-work is so bad that I kept playing just to see if it would get any worse as I went further in the game! Nothing like a film-noir-ish (or, say, Max Paynesque) dialogue written in German and then BADLY translated, topped off with people who seemed to have been dragged off the street and drugged before the voices were recorded.
I'm not sure if I want the sequel to have better VO's or not

Half of the fun was the campy voice work!
