Yeah, it's not the same thing if it's not on PC is it. I used to love playing that when it first came out, sneaking games in when the boss wasn't watching, and all that.
I think that was where my love of the FPS started.
What I love from the Wolfenstein (I only played Return to castle W.) is that it shows the real fact that nazis looked for paranormal things (what is only shown by Spielberg and specialized authors). The atmosphere is quite realistic, you experience the WWII and suddenly you are surrounded by zombies and mec-enemies.
