I used to go to my friends after school for many months in middle school just to play this game with him and get a little further. Ultra-challenging and mind-bending puzzles make this an absolute classic for me. The multiplayer is perfect, the cheats are hilarious, and the story and atmosphere is everything I ever want in a video game. With a balance of puzzles and action, great interactive environments and never feeling too big or too small, I've got to put this one in my list of all-time favorites.
