This document provides guidance on writing an effective treatment for a video game. It defines a treatment as a narrative version of a story that describes the main action and flow without dialogue. The document lists elements that should be included in a treatment, such as characters, costs, and story complexity. It also provides dos and don'ts for writing a treatment, advising to use prose over lists and to anticipate player choice rather than dictate a set path. Descriptions rather than brief lists are also recommended to fully outline the game world and story.
