Cinematic platformers are a small but distinct subgenre of platform games, usually distinguished by their relative realism compared to traditional platformers. These games focus on fluid, lifelike movements, without the unnatural physics found in nearly all other platform games.[12] To achieve this realism, many cinematic platformers, beginning with Prince of Persia, have employed rotoscoping techniques to animate their characters based on video footage of live actors performing the same stunts.[13] Jumping abilities are typically roughly within the confines of an athletic human's capacity. To expand vertical exploration, many cinematic platformers feature the ability to grab onto ledges, or make extensive use of elevator platforms.[12]
