The document provides guidance for developing a game idea, including sources of inspiration, describing the idea, and details for "Mission #3" where students will present and pitch original game ideas. Students are instructed to draw from dreams, other media, existing games, and idea generation tools when developing their concepts. The game idea should be described in 1-3 sentences or a short paragraph covering the goal, main player activities, and what makes the game unique. For the mission, each student will have 3 minutes to pitch a new game idea to the class, with the best ideas voted on and teams formed to develop them further.
