Naturally the MPEG hardware and lower resolution of your TV is more suited to showing video than the PC which has to interlace the movie with black lines to keep the frame rate acceptable. The character control is much more responsive, and there is no lag time from when you punch a button on your controller to the actual movement of the character. I struggled with the PC controls and got through, but the N64 controller was so imprecise that I simply stopped playing and gave up when I got to that part of the game. While the story is good and makes for a fun and interesting movie, most gamers won't want to take the time to read the lengthy plot synopsis. The N64 version begins to fall apart when you start to play it.
Control is horrible.
The analog stick on the N64 controller is overly sensitive and you will find yourself getting attacked and killed simply because you cannot turn and maneuver quickly enough to attack or defend yourself. Even when there is no enemy in sight it is quite difficult to just run around and explore your surroundings. Moving the stick up will always move your character forward in the direction you happen to be facing, but changing that direction accurately and smoothly is almost impossible. No matter which platform you choose, Nightmare Creatures is just an average game at best. There isn't much to do, and after the first 3 or 4 levels things will become repetitive and boring.
