True or False according to Josh Petrie: "An “engine”; is a collection of robust, reusable software subsystems (possibly including both code libraries and tools) designed to facilitate the development of actual games by addressing specific requirements. The requirements tend to be broadly defined: rendering, audio, physics, et cetera. Particularly ambitious engines that address multiple broad requirement groups tend be to known as “game engines” rather than just “graphics engines” or “physics engines”."
