The first game was ok-ish. The level design was a bit like Counterstrike. Straight forward, with 2 different ways to go, at max. Very small levels. Like a console port.
Plus: After the nazis caught you, you could easily escape without killing anyone.
I never had the need to play it twice. I had choosen the happy medium solution, being asked about half a dozen times whether I wanted to choose the good or bad ending. I was almost annoyed. Like the game didn't accept my choice.
