The first time i played was back in 2009, when I went over to a friends house. He loaded up WaW, and he asked me if i wanted to play with him. I said sure. I thought he was going to load up a game of multiplayer or something. But when it started loading, i saw the NDT cut scene. I looked at him with a confused look on my face and he started laughing. The game started and like that i was hooked. Of course i had no clue what i was supposed do do. That was probably the thing that got me addicted was the mystery when I first played.
