This project delves into the multifaceted world of game design and development. It begins with an exploration of idea generation techniques employed by industry professionals, including storyboards, brainstorming, mood boards, sketches, and the SCAMPER method, alongside a discussion of factors contributing to successful game ideas, such as connection, management, engagement, and decision-making. The project then moves on to game ideas and design considerations, categorizing various game genres like action, adventure, role-playing, simulation, strategy, sports, and puzzle games. A significant portion of the project is dedicated to preparing a detailed game design proposal, exemplified by a sports game focusing on car and bike racing, including features like customizable vehicles, power-ups, and virtual currency. Furthermore, the project outlines the process of creating a functional game prototype using industry-standard tools, emphasizing the transition from paper to software design, user interface prototyping, virtual prototype creation, adding input/output, algorithm engineering, and iterative testing and revision based on a requirements, analysis, and design model. The project concludes with a discussion of gameplay mechanisms, testing procedures, and the development process involved in producing a game prototype.
