Abstract: The age of transmedial entertainment is upon us, and videogames are pushing storytelling boundaries like never before. Audiences expect much more from a videogame based on a popular film, book, or comic franchise, whether it be a single player console game, massively multiplayer online game, or a mobile game. The challenge of how to capture the essence of an IP in game form is more important than ever. By exploring how to analyze properties for action words unique to that property and, thus, giving concrete form to their inherent game-like aspects, game writers can create a road map for user experience which takes special advantage of the IP's value. Attending writers will use this method to analyze past examples of game adaptations and transmedia game extensions, including those based on the James Bond franchise and George A. Romero~Rs zombie films. Writers will walk away with practical tools for collaborating on innovative, exciting, and risk-conscious games that will widen a game's appeal beyond the hardcore market. Idea Takeaway Writers will come out of this workshop with a practical strategy for how to collaborate on games that will reach (rather than exclude) the wide audience that make popular transmedial IP's attractive to publishers. Attendees will learn a simple method - derived from Miyamoto and Crawford - for quickly focusing the game design process around an IP's unique game-like qualities. This method can be used on multiple levels in a game company, from brainstorming core mechanics design to developing an overall business and marketing strategy. Intended Audience This workshop is intended for game writers, designers, and marketers looking for practical tools to help them get the most out of IP and reach a wider audience. Attendees should be familiar with IP-based game development and have a basic understanding of the game design process.
