Conkers Bad Fur Day. No single game has ever kept me as into it as that game has. the graphics, the story, the jokes, the characters, the controls, the sound, the replayability, all perfect. sure it was hard as hell, and it might be hard for some people to get through some parts (coughbeeandsunflowersexscenecough). but that was one of the things that made it truely amazing.
