Since the Horror movie is the obvious choice for fear inspiring movies, we must investigate the possibility of creating good horror in Machinima. Machinima has always been a great method for getting people who perhaps don't have the technology to create a real life film the chance to make their own. This isn't necessarily a bad thing as the game engines are specifically designed for this kind of situation. Most games that are used as Machinima engines are full of weapons and cool looking effects, not to mention pre-done futuristic textures and default models and sounds. Sci-fi action movies seem to be the obvious choice for early Machinima movies created by production teams, and they can be just as good as any other movie.
Terror is the sudden shock of horror movies, i.e. sudden movements or unexpected shocks.
Horror plays more on the psychological aspects, i.e. the anticipation of something happening or someone creeping round a dark haunted house. Based on the Cthulu Mythos, a horrific story in itself, it was a perfect chance to use the Quake series for something different. In Nightfall, the second part of the series, created in Quake 2, the setting was nothing like in the game. It seemed approximately present day, using new models and maps which suited the film and even new animations including full hand to hand combat sections. The people who do not know the freedom and possibilities of Machinima, have all said the same thing about Machinima horror.
